Air, with a mass of 1.5 lbm, is initially at 2000°F. In a cooling process, the internal energy of the air is reduced by 350 Btu. Determine the final temperature of the air if (a) the specific heat is considered constant, with its value taken at 2000°F, (b) the specific heat is considered constant, with its value taken at 100°F, and (c) considering the specific heats to be variable.
Given: m = 1.5 lbm; T1 = 2000oF; ?U = -350 Btu What will be an ideal response?

The concentration of carbon monoxide (CO) in a gas sample is measured by a spectrophotometer and found to be85 ppm. Through long experience with this instrument, it is believed that its measurements are unbiased and normally distributed, with an uncertainty (standard deviation) of 8 ppm. Find a 95% confidence interval for the concentration of CO in this sample.
