metabolic rate by allowing the organism to interact with changing temperatures form 5oC to 40oC. In the laboratory, the animal was placed in a closed chamber, were the flow of gases was recorded, and the change in Oxygen intake was recorded using a gas sensor. Indirect calorimetry was employed. The data outcome shows a linear relationship between the animal’s body temperature and the ambient temperature, while also showing a small exponential relationship with steady increments of both the O2 consumption

Experiment #6 Determination of the solubility product of PbI2 Introduction: The purpose of this lab is to get familiar with the concept of solubility by determining the concentration of PbI2 and Pb2+ in the slightly acidic solution and to calculate the solubility constant using the equation Ksp=[Pb2+][I-]2 . Safety: Safety glasses must be worn at all times. Gloves are recommended in order to avoid the direct contact between skin and the chemicals. Avoid the spill of chemicals during shaking

where pIGN represents the unburned gas pressure measured at spark ignition time, TIGN its temperature, evaluated by the use of equation (5), while m is the polytropic coefficient: this has been determined as the opposite slope of least square regression line representing Log p as function of Log V from 80 to 40 crank angle degrees before TDC. This procedure, applied to each single pressure trace, allowed taking into account the different heat transfer levels related to the several different compression

Project Part 1 Everyone’s Gasoline Price When looking at the history of gas prices they seem to constantly fluctuate over the years. I remember before I was legally able to drive how the gas prices were extremely low. I remember going to fill my mother’s car with her and saw the gas prices were $1.10 a gallon! When I look at gasoline prices now I wonder about what happened to those times now that I am driving. After a little research into the topic I found that there are many different factors

(Barium), Si (Silicon), N (Nitrogen), F (Fluorine). * Exercise 132 in Ch. 11 * Aerosol cans carry clear warnings against incineration because of the high pressures that can develop upon heating. Suppose a can contains a residual amount of gas at a pressure of 755 mm Hg and a temperature of 25 °C. What would the pressure be if the can were heated to 1155 °C? * Answer: Residual pressure: 755 mm Hg = 0.993 atm * Final pressure = ? * Start temperature
