2. mant pressure. Why is this so? Use data in Table B.2 to calculate the following: (a) The heat capacity (C) of liquid benzene at 40C. (b) The heat capacity at constant pressure of benzene vapor at 40C. (e) The heat capacity at constant pressure of solid carbon at 40C. (d) AA (kJ/mol) for benzene vapor going from 40C to 300C. (e) A (kJ/mol) for solid carbon going from 43C to 300C
