the volume of a gas varies inversely as its pressure and directly as its temperature.

A certian gas occupies a volume of 2.3L at a temp of 380 K and a pressure of 20 N/cm^2

find the volume when the temp is 342 K and the pressure is 10 N/cm^2

1 answer

since v = kT/P,
PV/T is a constant. So,

342*V/10 = 380*2.3/20
