The constant-pressure heat capacity of a sample of a perfect gas was found to vary with temperature according to the expression cp/(J K?1) = 20.17 + 0.3665(T/K). Calculate q, w, ?U, and ?H when the temperature is raised from 48°C to 220°C at the following conditions.
(a) at constant pressure
q,w,delta u, and delta h
(b) at constant volume
q,w,delta u, and delta h
