Ballon problem, adiabatic

  1. Apr 3, 2008 #1
    I need to solve this problem.

    A big balloon with volume V1 = 2.00 * 10^3 m^3 contains helium at 15 degrees celcius and 1 atm. The balloon now rises from the ground to a height 'h' where the pressure is 0.900 atm. The process is adiabatic:

    a) find the volume at height h

    b) find the temperature at height h

    c) find the increment in the internal energy of the helium from the ground to the height h.

    I get:
    c)
    dU = -W = -1.25*10^4*kJ

    does this seem to be a likely result?
