In Physics, when temperature is constant, the volume of gas is inversely proportional to the pressure. When the volume is 0.08 cu. ft, the pressure is 1500 psf. Find the volume when the pressure is increased to 4000 psf.
- 0.01 ft3
- 0.03 ft3
- 0.04 ft3
- 0.06 ft3
Answer
B. 0.03 ft3
Solution
By Boyle's Law, P1V1=P2V2. V2 = P1V1/P2 = 1500(0.08)/4000 = 0.03 ft3.
