Question

Find the number of following functions which are macroscopic properties. Pressure, Volume, Enthalpy, Work, Heat, Gibbs energy, temperature, Internal energy, Entropy.

Answer 1

7

Answer 2

Macroscopic properties are state variables of a system, measurable without considering microscopic details. Pressure, Volume, Enthalpy, Gibbs energy, Temperature, Internal energy, and Entropy are state functions, hence they are macroscopic properties. Work and Heat are energy transfers during a process (path functions), not properties of the system's state. Therefore, there are 7 macroscopic properties in the given list.
