User: 20 cubic inches of a gas with an absolute pressure of 5 psi is compressed until its pressure reaches 10 psi. What's the new volume of the gas? (Assume that there's no change in temperature.)
A. 10 cubic inches
B. 5 cubic inches
C. 100 cubic inches
D. 40 cubic inches
Weegy: 20 cubic inches of a gas with an absolute pressure of 5 psi is compressed until its pressure reaches 10 psi. The new volume of the gas is 10 cubic inches.
Solution:
V2 = P1,V1 / P2;
V2 = 20 × 5 / 10;
V2 = 100/10;
V2 = 10 cubic inches.
