Homework Statement
Air is heated from 300 to 350K at constant volume, Find 1Q2.
Homework Equations
1Q2 = m(u2-u1)+1W2
u2-u1 = cv(t2-t1)
The Attempt at a Solution
The PV diagram of the process is straight up, so the area under the curve is 0, so the work done is zero.
Cv is .717 from the back of the book
1Q2 = m*.717(350-300)+0
How do I find the mass? I don't think I'm doing it right.
