Eric Klinenberg‚ assistant professor of sociology at New York University (formally of Northwestern University)‚ wrote "Heat Wave: A Social Autopsy of Disaster in Chicago" in order to further investigate the devastating Chicago heat wave of 1995. From July 13h to July 20th‚ the heat led to over 700 deaths and thousands being hospitalized due to heat related illness. Following the catastrophe‚ there have been numerous medical‚ meteorological‚ and epidemiological studies done examining the reasons for

Molar Heat of Combustion Aim: To find the molar heat of combustion for four different alkanols: 1. Methanol 2. Ethanol 3. 1-Propanol 4. 1-Butanol - And to compare the experimental value with the theoretical. Background: The Molar Heat of Combustion of a substance is the heat liberated when 1 mole of the substance undergoes complete combustion with oxygen at standard atmospheric pressure‚ with the final products being carbon dioxide gas and liquid water.

the water would need a set amount of energy to break through the changes in matter. This is why temperature slows down in these phase changes. 2. When the ice is melting is it releasing heat or absorbing heat? Explain your answer. It is absorbing heat as it tries to achieve thermal equilibrium with the incoming heat. The water has more energy‚ which is why the water goes to a more easy to move around “phase” form from

Lab 7: Geologic Time 9 Answer Sheet Name(s) 1. As an example of how radioactive decay works‚ the TA may lead a small demonstration. Each student will receive one penny and stand up. At this point all of the students are parent isotopes. Every student should then flip their penny. Students whose penny lands heads-up should sit down. These students who are now seated are now daughter isotopes. The remaining standing students should again flip their penny‚ and students whose penny lands heads-up

YOU THINK YOU CAN HANDLE THE HEAT? Mike Lupica’s book Heat has all of the elements that a story needs to have. It has a setting and a theme. It has a plot and a conflict. And what kind of book doesn’t have any characters. Also the story was interesting. Not all stories can appeal like Heat. If you like baseball you would agree that this book is interesting. Heat is about a kid who can’t seem to prove his age after moving to New York from Cuba. His dad has died so he has no contact with Cuba. Also
