| A. | \(\mathop \smallint \limits_{{T_1}}^{{T_2}} {C_p}dT\) |
| B. | \(\mathop \smallint \limits_{{T_1}}^{{T_2}} {C_p}dT + \mathop \smallint \limits_{{p_1}}^{{p_2}} {\left( {\frac{{\partial V}}{{\partial p}}} \right)_T}dp\) |
| C. | \(\mathop \smallint \limits_{{T_1}}^{{T_2}} {C_p}dT + \mathop \smallint \limits_{{p_1}}^{{p_2}} \left[ {V - T{{\left( {\frac{{\partial V}}{{\partial T}}} \right)}_p}} \right]dp\) |
| D. | \(\mathop \smallint \limits_{{T_1}}^{{T_2}} {C_p}dT + \mathop \smallint \limits_{{p_1}}^{{p_2}} \left[ {V - T{{\left( {\frac{{dV}}{{dP}}} \right)}_T}} \right]dp\) |
