FORMAL REPORT ON HEAT CAPACITY RATIOS OF GASES ABSTRACT This report discusses an investigation of the heat capacities of Helium‚ Nitrogen‚ and Carbon Dioxide. To accurately determine experimental values for the heat capacity of each gas‚ the heat capacity ratio was calculated from measurements of the speed of sound in each gas. An apparatus designed to measure the wavelength and frequency of sound waves in each gas was used to determine the speed of sound as a frequency was passed through each

Classis heat stroke usually affects sedentary elderly individuals‚ chronically ill persons‚ and young persons. Exertional heat stroke occurs more often in younger‚ healthy individuals who actively in strenuous physical activities . Classic heat stroke caused by exposure to particularly hot environment for a long periods of time. Exertional heat stroke caused by an intense activity in a hot environment. The symptoms of heat stroke include high body temperature‚ mental changes‚ for instance confusion

Heat of Mixing: Ethanol and Water Abstract The temperature change when known amounts of water and ethanol were mixed was determined to see the enthalpy change in an isothermal and isobaric environment. Agreeable data was found compared to similar experiments. As the mole fraction increased of the solution so did the enthalpy until a certain limit of about 0.32. Since water’s structure and unique properties affect many aspects of a solution‚ the solutions enthalpy’s decreased at a certain time

Understand and observe the concept of Heat Transfer‚ by measuring the temperature distribution for steady state conduction of energy through a specific efficient unit. • Understand the Fourier Law of heat conduction and the usage of its equation in determining the rate of heat flow via solid materials. II. Theory : The Fourier Rate Equation: When a plane section of ∆x and a constant area A maintains a temperature difference ∆T‚ then the heat transfer rate per unit time by conduction

Since the Miami Heat have won their second franchise championship there has been a lot of speculation on the next moves the organization as far as the who will be on next years roster. Ray Allen‚ a future hall of famer‚ is a highly sought after 3-point sharpshooter who is an unrestricted free agent. There has been much controversy in regards to what team will be a best fit for the 37-year-old veteran. According to a blogger on the Bleacher Report he feels that it would be sacrilegious and cowardly

Conference fourth leading and Southeast Division top team Miami Heat outlasted the East’s fifth ranked Atlanta Hawks 115-111‚ even playing without key players Chris Bosh and Dwayne Wade Friday night at the Philips Arena in Atlanta. Luol Deng paced the Heat scoring with a team-high 30 points and 11 rebounds to go along with 4 steals in 37.31 minutes in the hardcourt as Miami moves up a spot in the conference’s team positions. The Heat is now having a record of 30 wins and 24 losses‚ and currently 14-13

The Effects of Using the Heat Shock Treatment to Deliver a Vector in Genetic Transformation Introduction: In this experiment we are testing what is required for E. coli to successfully grow on LB (Luria Broth) plates with ampicillin and determining if any genetic transformation has occurred. By combining +pGLO LB and ampicillin we should get an ampicillin resistant gene and by using –pGLO we should create a non-genetic resistant bacteria. The pGLO plasmid has the GFP (green fluorescent protein)
