A cylindrical figures contains a gas and we have a piston that is capable of changing the gases volume.
Initial state: V0=1l P0=10^5p T=300°K
We pressurize on the piston that has a mass m=300g and a surface S=20cm^2.
The new temperature T1=540°K
Calculate the change in internal energy.
The Attempt at a Solution
Well I know that the change in internal energy is: ΔU=W+Q or ΔU=-P1(V1-V0)
and that p=F/S. but since my teacher didn't explain the lesson well enough I have no clue on how to answer it. Any help would be very well appreciated.
