# Ideal gases questionWatch

#1
The initial vol. of a gas is 0.2m^3 at a temp of 27ºc and a pressure of 1.0 x 10^5 Pa. After compression the vol of the gas is 0.070m^3 and the temp is 57ºc. Find the final pressure of the gas.

No clue whatsoever on how to do this...

I know that P=F/A and that temp is a measure of the avg KE of the molecules but don't know how to relate everything!

Anyone can help me?

Use the ideal gas equation: PV/T = constant

p1V1/T1 = p2V2/T2 as thomask says above (PV/T is constant)

Dont forget that temps need to be in Kelvin.

You know that:

You just need to sub in these values and rearrange the equation for
