Question 1048891: the volume V of a given mass of a gas varies directly as the temperature T and inversely as the pressure P. If V=231cm^3 when T=300 degrees K (Kelvin) and P=20lb/cm^2, what is the volume when T=320 degrees K and P=16 lb/cm^2?

the volume V of a given mass of a gas varies directly as the temperature T and inversely as the pressure P. If V=231cm^3 when T=300 degrees K (Kelvin) and P=20lb/cm^2, what is the volume when T=320 degrees K and P=16 lb/cm^2?
------------
PV = nRT
---
P*V = k*t
---
You can solve for k, then solve the problem, or solve it as a proportion.
-----
P*V = k*T
20*231 = k*300
k = 20*231/300 = 15.4
=========================
P*V = k*T = 15.4T
V = 15.4T/P = 15.4*320/16
V = 308 cubic cm
