A 45m long steel measuring tape is calibrated for use at 20 degrees C.

a) What is 20 degrees C in F and K?

b) How long is the tape on a hot day with T=35degrees C and a cold day with T=-10degrees C?

c) If you use the measuring tape to measure a piece of aluminum to be 15m when the temperature is 20degrees C, what length do you measure when the temperature is 35degrees C?

d) You fill your car tires to a gauge pressure of 22kPa on a cold morning (T=0degrees C) and drive to the dessert where the temperature is 36degrees C. Assume the volume of air is the same and the tires have come to thermal equilibrium with the ambient temperature. What is the new tire gauge pressure? Assume at both locations the atmospheric pressure is the standard 1 atmosphere.

It is recommended that you inflate the tires on your car when they are at ambient temperature. Suppose you inflate the tires to 35 psi gauge with air at T = 20 °C. The tire heats up when you drive to 37 °C. Additionally, because the tire is spinning, it expands due to centripetal effects and the volume of the tire increases by 3%. What is the gauge pressure in the tire now?

You have a glass of water at 83 degrees C. You want to boil it by putting it in a vacuum. What is the smallest percentage of air molecules you would have to remove from the vacuum chamber to allow it to boil? Hint: to boil, the vapor pressure of water must be equal to the external pressure. (You will have to refer to a chart to figure out the vapor pressure of water at 83 degrees). (Remember, atmospheric pressure...
