Thermodynamics Question - Should be pretty easy

  1. Nov 1, 2011 #1
    1. The problem statement, all variables and given/known data

    I'm trying to understand this concept of pressures and volumes changing and how it effects the temperature. Is my understanding correct so far?

    If pressure is changing but volume is constant is

    Final Temperature = Initial Temperature + (something) ?

    If this is right so far, I'm stuck on coming up with the "something" value. If it is wrong, how can I determine this?

    Thank you

    2. Relevant equations
    PV = NKT
    (U2 - U1) = (1/2) * NKfT

    If PV=nRT and V is constant then:

    P/T = constant

    So:

    Pf/Tf = Pi/Ti

    or:

    Tf/Ti = Pf/Pi
