Type and density of liquid Essay Example for Free

Type and density of liquid Essay These are the variables that I could choose to focus on. I have chosen to focus and adapt on the idea of insulation. Prediction I predict that the more insulation (layers) there is, the smaller the reduction in heat. I think this because when the outside air tries to touch the container to cool it, it will be stopped by the insulation, so it will take longer to cool. Also, when heat tries to escape from the container, it will go into the first layer of insulation, which will then absorb the heat. It would then still keep the container warm, not letting as much heat out as fast. I also predict that if I have a lid it will take even longer to cool, because, as you can see in the picture below, evaporation will also take place. If I have a lid, the heat will then be stopped from escaping into the air through the top. As shown below- Equipment   Timer- this is to time the amount of time the liquid is in the container. This will make sure that the time will be the same for each experiment.   Data logger and Thermometer- this is to take the temperature of the water. I will use two forms of identifying the temperature. This way I can compare the two results and see if there are any drastic differences. Also, a datalogger is accurate, but I will still use a thermometer to back up my results.   Insulation Material- I am going to use a foam type material as my insulation.   Clamp- I will use a clamp to hold both the datalogger and thermometer above the container.   Container- I am going to use a glass beaker to hold the liquid. I am using this instead of a polystyrene cup, because the cup would hold residue heat, which would affect our results. Also a polystyrene cup is already quite insulated. * Kettle- this is to heat the liquid before I put it in the container. I will clean out the kettle, to make sure there is no black, therefore the heat will be reflected back into the kettle, instead off being absorbed. This should help it to reach its highest temperature. I will make sure that there is 1litre of water in the kettle each time put it on to boil. Measuring Apparatus- I will put the water directly into the glass beaker, measuring it in there. Lid- To put over the glass beaker to try and prevent evaporation. Fair Testing and Other Factors that need to be controlled There are things that I will need to try and make sure are the same throughout my experiment. These are: Amount of liquid- I will have to make sure that each time I refill the glass beaker I have the same amount of liquid. To do this I will measure it in some measuring apparatus. Each time I will use the same type and size of measuring apparatus, for the same accuracy. To make this even fairer I will simply measure the amount of water in my glass beaker, so I know that it will always be the same. Temperature of surroundings- there is not much I can do to control this, but to make sure there is no drastic change, I will stay away from radiators and places in direct sunlight. Shape, Colour, Size, Surface Area and Thickness of container- will have to be the same throughout my experiment to keep it fair and to get reliable results. For instance, if I had a different colour container each time I did my experiment it would affect my results. This would be, because instead of reflecting the heat back in, if I had a black container it would absorb the heat. To make sure of this I will use the same container each time.   Temperature of liquid to start- I will try to keep the around the same. If I cannot keep the temperature the same I will just measure the difference between the two (start and end). Type and Density of Liquid- I will keep using the same type of liquid throughout my experiment because some types may loose heat at a different rate than others. I will use water because it is easily available, and it is the same each time.   Surface container is on- will have to be the same. If for example I was to put it on a foam surface one day, and something different another day, it would affect how much heat is lost. This is due to the surface acting as insulation.   Lid- I am going to use a lid each time. This should stop a lot of heat reduction through evaporation, which I have already explained in my prediction.

The Ubiquitous Media Essay -- Argumentative Persuasive Topics

The Ubiquitous Media    The news media is an ubiquitous presence in our times. Whether it is the switching of a television channel, turning a radio dial, signing on the Internet, or glancing at a newspaper, the media is present. It is a social infrastructure that was created to inform citizens of happenings, but has now become a multi-billion dollar association of corporations and advertising agencies. The real price of the media is incalculable because of how it shapes and molds our views of the world. This influence for the most part is positive and horizon expanding but may have negative connotations.    The news media is limitless. It provides for me all the basic factual information I need in order to be an informed citizen. By reading a newspaper or watching the evening news, I gain a wider view of the world. My opinions are formed partly by the news because of the facts given. My viewpoints are not formed entirely by the news media though; there is a definite difference between believing and simply listening.    Some of America tends to be easily inf...

Brutus in an Honorable Man.

Estne Virtus? Confucius said that, â€Å"People with virtue must speak out; people who speak are not all virtuous. † Confucius lived in China around 500 BCE and voiced novel opinions on virtue, politics, ethics, and other abstract ideas. Even today, thousands of years later, many people believe in Confucianism. Confucius was very vocal. In Shakespeare’s Julius Caesar no man is more vocal than Brutus. He assassinates Caesar, pleads to the people for their support, and conducts war with Octavian and Marc Anthony. But is he virtuous? Brutus is not necessarily virtuous; he does all of these actions to gain glory and to show his virtue. Everyone should aspire to be virtuous. However, as seen by Marc Antony and Cassius manipulating Brutus and Brutus’s death, excessive pursuit of virtue can be detrimental. Brutus’s excessive obsession for virtue leads to his failure. Brutus loves Julius Caesar; however Cassius manages to turn Brutus against Caesar by taking advantage of Brutus’s obsession with virtue. Cassius urges Brutus to â€Å"think of the world† and kill Caesar for the good of Rome (1. 2 329). Cassius explains to Brutus that Caesar must be killed in order to preserve Rome, and not because of any other reason, like Cassius’s jealousy. Cassius explains that Caesar is unfit, saying that â€Å"Caesar cannot even swim†, and unworthy to rule Rome, saying that Brutus is more fit. Brutus does not respond to the statements made by Cassius, and draws more attention to the â€Å"general shout[s]† of the people (1. 2 139). Brutus avoids the questions and must â€Å"recount hereafter† of Cassius’s reasoning, Brutus needs time to consider if the conspiracy is virtuous or not (1. 2 174). If virtuous, then he will act. Although Brutus does admit that â€Å"Brutus had rather be a villager / than to repute himself a son of Rome / under these hard conditions at this time / is like to lay upon us† (1. 181-184). Brutus dislikes the dishonor that the tyranny of Caesar brings to Rome. He thinks it detracts from his own virtue. He cares for his virtue. Later on, Cassius also sends letters to Brutus posing as Roman citizens. Cassius gives Brutus the impression that citizens beg him to â€Å"speak, stri ke, and redress† (2. 1 49). When Brutus thinks that the people want Caesar to fall, Brutus tells himself that he joins the conspiracy for the people. In actuality, he joins the conspiracy not to preserve the Republic but to show virtue, to look better, more virtuous, in the eyes of the Roman people. Brutus is not concerned for the people, but for his image when he joins the conspiracy. Brutus should kill Marc Antony when he has the chance, and not be so concerned for his own image. For instance, when Cassius proposes to Brutus that they kill Antony along with Caesar, Brutus thinks that by killing Antony the people will look to him as â€Å"butcher† and not a â€Å"sacrificer† (2. 1 179). Instead, Brutus wants the conspirators to â€Å"[appear] to the common eyes† as â€Å"purgers, not murderers† (2. 1 192 193). This shows that Brutus bases his choices on whether or not people would view him as virtuous. Although, he acts foolishly, for he not only prevents the conspirators from killing Antony, he allows Antony, Caesar’s right hand man, to speak last in Caesar’s funeral. To Brutus, Antony â€Å"can do nothing more than Caesar’s arm / When Caesar’s head is cut off† (2. 1 195-196). Brutus lets Antony speak because it would be viewed as an act of kindness and forgiveness to what was an enemy previously. When Antony enters the pulpit after Brutus, he wins the crowd and convinces them of the conspiracy’s evil. The crowd, the Roman people, now want to set â€Å"fire [to] the traitors’ houses† (3. 269). Brutus thinks he fights for the people, though the people think otherwise. If Brutus had killed Antony, and not been so concerned about virtue, Brutus would have been able to remain in Rome, remain loved by his people. Brutus commits suicide because he believes that doing so will cause people will think of him as virtuous. Brutus is lef t to fight Antony and Octavian by himself at Philippi because Cassius kills himself. Knowing the circumstances, Brutus would rather â€Å"leap in [the pit himself]† than â€Å"tarry till they push [him]† (5. 28-29). Brutus would just as soon kill himself than have himself killed. His reasoning come from the Roman belief that when a person faces dishonor, maybe a military loss, killing oneself is a virtuous way to still obtain honor in spite of what occurred. He declares â€Å"I love / the name of honor more than [he] fear[s] death† and so he runs onto his sword (1. 2 95-96). In doing so Brutus has now doomed the preservation of the Republic for the people. If Brutus had cared for the people, he would have continued to fight for them. Brutus shows that, ontrary to what he says, he has the most concern for his own image and not the well-being of the Roman people. Brutus is a selfish man, not a virtuous man. Brutus fails not because he obtains an excessive amount o f virtue, but because he hunted for virtue excessively. He hunts for glory and virtue so obsessively that he loses sense of what he believes in. Brutus is known to many as the man of great virtue. Although, the virtue of Brutus is forced, unnatural. In the end, this in itself is not virtuous. Virtue, or any characteristic, comes from the manner in which an action is performed and not the result. Odysseus is a similar man. He does many virtuous acts, although he acts knowingly that his effect, the result of his actions, will be virtuous. Odysseus took on both Scylla and Charybdis, evil sea monsters, so he himself could demonstrate his superior virtue. Many of his shipmates, and nearly himself, are killed. Odysseus survives become more â€Å"virtuous,† more â€Å"honorable,† for surviving both monsters. Although, if one looks towards how these men performed these actions, they see no virtue. After all, it is not what one does, but how one does it.

Case Study vs Interviews, Focus Groups, Textual Analysis, Ethnography, Biographical Research, Panel Surveys Free Essay Example, 1750 words

The usual rules and guidelines of an ordinary research and social sciences must be strictly adhered to (Yin 38). The events and activities that are stated in the resource must be recorded according to their chronological occurrence. The order in which the information was recorded should be systematic not to leave out any important detail. In-depth report and informal interviews require social and close interactive interaction between the investigator and the interviewee. It is different from other kinds of interaction that may found in other fields such as public lectures and job interviews. They are based on building a relationship so as to be effective and useful to those that are involved. They are like the types of interaction that one would witness between close friends. They are used in combination with other relevant data that had been collected that relates to the subject matter. This is in contrast with case study as more time is spent on a single interview whereas case study dwells on a sample. Focus groups and Case study. It is very significant and useful in social sciences.
