20 cubic inches of a gas with an absolute pressure of 5 psi is compressed until its pressure reaches 10 psi. What is the new volume of the gas? (Assume that there's no change in temperature.

Initial volume of the gas (V1) = 10 inches^3

Initial pressure (P1) = 5 psi

Final pressure after compression of the gas (P1) = 10 psi

Let us assume the final volume of the gas (V2) = x

According to Boyle's Gas law, the pressure and volume of a gas remains constant under ideal condition. Then

P1V1 = P2V2

5 * 10 = 10 * x

50 = 10x

x = 50/10

= 5 cubic inches

So the volume of the gas after it was compressed was 5 cubic inches. I hope the procedure is clear enough for you to understand.
