Question
The total air pressure in a tire ( gauge pressure + atmospheric pressure) is measured to be 37.7 Ibs/im^2 on a warm summer day when the outside temperature is 23 degree C. what would be the new tire pressure when the temperature drops to freezing ( 0 degree C) ? Assume the volume inside the tire stays constant.
A. 34.8 lbs/in^2
B. 22.7 lbs/in^2
C. 40.6 lbs/in^2
D. 14.7 lbs/in^2
The cooling process describes
A. Is Isothermal
B. Does not accomplish any work because the volume is constant
C. Is Adiabatic
D. Is Isobaric
Explanation / Answer
The total air pressure in a tire ( gauge pressure + atmospheric pressure) is measured to be 37.7 Ibs/im^2 on a warm summer day when the outside temperature is 23 degree C. what would be the new tire pressure when the temperature drops to freezing ( 0 degree C) ? Assume the volume inside the tire stays constant.
A. 34.8 lbs/in^2------(apply P1/T1 = P2/T2---> T2 = 37.7*273/300 = 34.3 lb/in^2)
B. 22.7 lbs/in^2
C. 40.6 lbs/in^2
D. 14.7 lbs/in^2
The cooling process describes
A. Is Isothermal
B. Does not accomplish any work because the volume is constant
C. Is Adiabatic
D. Is Isobaric
