For an ideal gas, (i) the change in internal energy in a constant pressure process from temperature T_1 to T_2 is equal to nC_V(T_2-T_1), where C_V is the molar heat capacity at constant volume and n is the number of moles of the gas (i) the change in internal energy in a constant pressure process from temperature T_1 to T_2 is equal to nC_V(T_2-T_1) For an ideal gas where C_V is the molar heat capacity at constant volume and n is the number of moles of the gas September 10, 2021 Category: Cengage NEET by C.P Singh , Chapter 21 - Laws of Thermodynamics , Part 1 , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
