WebFor a temperature change at constant volume, dV = 0 and, by definition of heat capacity, d ′ QV = CV dT. (31) The above equation then gives immediately (32) for the heat capacity at constant volume, showing that the change in internal energy at constant volume is due entirely to the heat absorbed. To find a corresponding expression for CP ... WebThe total number of degrees of freedom for a linear molecule is 5 so its internal energy is U = 5/2 RT, its molar heat capacity at constant volume is Cv = 5/2 R and its molar heat capacity at constant pressure will be Cp = 7/2 R. A nonlinear molecule rotates along …
