A cylinder contains 12L of oxygen at 20 degree celsius and 15atm. The temperature is raised to 35 degree celsius,and the volume is reduced to 8.5L. What is the final pressure of the gas in atmospheres?Assume that the gas is ideal. (answer in atm)
The answer is 22.

For an ideal gas, Presion(atm)xVolume(lts)/Temperature(°K) is a constant, so, for a ideal gas, P1xV1/T1=P2xV2/T2 where V2 is the answer to the question.
