Homework Help: Isochoric process

  1. Nov 26, 2007 #1
    A 3.00-L tank contains air at 3.00 atm and 20.0 C. The tank is sealed and cooled until the pressure is 1.00 .
    What is the temperature then in degrees Celsius? Assume that the volume of the tank is constant.


    3/20=1/T, T=6.67 C

    Why it's not right?
