Heating at constant volume

Webconstant volume. (b) Heating at constant volume followed by cooling at constant pressure. Calculate the heat and work requirements and ΔU and ΔH of the air for each path. The following heat capacities for air may be assumed independent of temperature: C V = 20.78 and C P =29.10 J mol-1 K-1 Assume also for air that PV/T is a constant ... Web20 de mar. de 2016 · 1 Answer Sorted by: 5 Yes, you can apply the formula Δ U =nCv Δ T for an ideal gas in a container whether or not the process is isochoric. This is because the change in internal energy for an ideal gas undergoing some mechanical process is mainly affected by the change in kinetic energy of the gas.
