# 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 of volume of the gas?

Approx. $0.164 \cdot L$
Boyle's Law states that ${P}_{1} {V}_{1} = {P}_{2} {V}_{2}$. (Temperature and amount of gas constant)
Thus ${V}_{2} = \frac{{P}_{1} {V}_{1}}{P} _ 2$ $=$ $\left(5 \cdot \text{psi"xx20*"inch"^3)/(10*"psi}\right)$ $=$ ??"inch"^3.
