Thermodynamics Question - Should be pretty easy

Homework Statement



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

Homework 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
