Question 2
After heating 2 ft3 of gas at 50 psia from 300 R to 600R at 50 psia, the volume of the gas will be:
A) 2 ft3 because the pressure did not change.
B) 4 ft3 because the volume and temperature vary directly.
C) 1 ft3 because the temperature and volume vary inversely.
D) The final volume cannot be determined without knowing the specific gravity of the gas.
