Question

if 100ft^3 of atmospheric air at zero fahrenheit temperature are compressed to a volume of 1 ft^3 at a temperature of 200 degree fahrenheit, what will be the pressure of the air in psi?

Answer 1

P1 * V1 = P2 * V2

Where P1 and V1 are the initial pressure and volume, P2 and V2 are the final pressure and volume.

1 atm * 100 ft^3 = P2 * 1 ft ^3

P2 = 100 atm; use your book or the internet to find a conversion factor from atm to psi
