Physics (Please help!!!)

1) An ideal gas occupies a volume of 0.60 m^3 at 5atm and 400K. What volume does it occupy at 4.0atm and a temp of 200K?

I know how to find the volume with the m^3 and the atm but it threw me off since it gives the 4.0 atm and the temp 200K.

  1. The quantity P V/T remains constant when the number of moles remains the same.

    Therefore
    P1 V1/T1 = P2 V2/T2
    "V2" is the final volume.

    V2 = V1*(P1/P2)*(T2/T1)

    = 0.60 m^3 * (5/4)*(200/400)
    = ___ m^3

    An ideal gas with r(Gama) = 1.5 occupies a volume of 2.0 L. The gas expands isothermally to a volume of 3.0 L. Alternatively, the gas reaches the same final state by first adiabatically expanding to the final volume then heating
