This paper lists the values of slope properties of entropy, enthalpy and exergy along isotherms, isochors, isobars and isentropes in terms of properties that can be primarily measured, namely pressure, volume, temperature, their slopes derivable from equations of state and one of the specific heats in the ideal gas state. It is also shown that all these slopes can be expressed in terms of a coefficient of thermal expansion and isothermal compressibility as well. These could be useful as an educational tool in chemical and mechanical engineering.
