Which of the following statements is false?

a$.$ The constant volume heat capacity of an ideal gas is a function of temperature only.

b$.$ The internal energy of an ideal gas is a function of both temperature and pressure.

c$.$ There is no explicit "flow work" term in the generalized energy balance because flow work is accounted for in the enthalpy term.

d$.$ The specific volume of a liquid is frequently modeled as constant with respect to temperature and pressure.

e$.$ In some cases such as low pressures or low volumes, enthalpy and internal energy values are essentially identical.
