Asked by Sue
A volume of 140 cm3 of an ideal gas has an initial temperature of 20°C and an initial pressure of 1 atm. What is the final pressure if the volume is reduced to 120 cm3 and the temperature is raised to 40°C?

PV = kT, so PV/T is constant.
So, you want P such that
(P)(120)/(40+273) = (1)(140)/(20+273)
