Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube‚ shiny foil can be used because it’s a poor emitter of radiation and it will reflect escaping heat by reflecting‚ because this method is used in flasks to keep hot drinks warm. Though it is a good conductor so will lose heat through to surfaces its touching but it shouldn’t matter because it will be touching air and glass which both

comprehension or as I like to call it creativity. Funny Enough‚ I use the ocean‚ something so serene and effervescent to describe my annual quarter life crisis. Unconciously however‚ that must be no mistake‚ seeing that Water will be the theme of the experiment I will be working with. I’m still a little skeptical as to how I chose Water . There was no real inspiration‚ or interest on such force but rather an intuition that drove me to further explore this element. Perhaps an unconscious inclination

evidence and thorough research‚ Wilson and Sears’ theory on how the pyramids were built is the most convincing of the three. They provide proof that the Egyptians built the pyramids themselves with a variety of materials‚ such as wood‚ and how their religious beliefs likely sped up the construction process. While other explanations‚ such as von Däniken’s‚ focus on his own opinions and conspiracy theories (like his claim that extraterrestrials built the pyramids)‚ Wilson and Sears are realistic and back

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

English 10a 6 March 2012 Tuskegee Experiments This is possibly one of the most inhumane things to ever happen in the 20th century in the Untied States. The experiments that took place were the root of medical misconduct and blatant disregard for human rights that took place in the name of science. The ghastly medical expirements that took place between 1932 and 1972 was merely an observation of the different stages of syphilis. The men in these experiments for the most part were illiterate

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During
