💡 Solution & Explanation

1. S(entropy) is not the measure of available energy. 2. S  between the two states is not path dependent whether reversible or irreversible 2 1 S S S    . 3. Heat supplied into the isothermal reversible expansion of ideal gas is equal to work of expansion of the gas. 4. G  is equal to the available energy of the system to do useful work.
