Homework Statement
I'm confused by the different equations textbooks use for Q=mcΔT
I understand for solids/liquids its always Q=mcΔT but for gases am I right to say ΔH=Q=ΔU+pΔV=m(c_p)ΔT for constant pressure and Q=ΔU=m(c_v)ΔT for constant volume?
So if my textbook says "ΔU=n(3/2R)ΔT for any processes of monoatomic ideal gas" its wrong because for constant pressure processes you need to add work? Or am i getting something wrong.
Edit:
Answer is here : http://postimage.org/image/4f4wxp6b1/
What I really want to know is if I should use Q=nCt instead of U=nCt[\b] as the book did and why not(I think the book should be right...)
