Question

Calculate q, w, ?U, and ?H when the temperature is raised

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 28°C to 210°C at the following conditions.
(a) at constant pressure
q

w

?U

?H
(b) at constant volume
q

?U

?H
