What do u mean by entropy and enthalpy? write some differences between them.

Explanation:

Entropy: a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.

Enthalpy: a thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.

Differences: The main difference between entropy and enthalpy is, entropy is used as a measurement of the disorder or the randomness of a chemical process while enthalpy is used as a measure of the heat change of a chemical reaction or the change in internal energy of a reaction under constant pressure. Entropy is measured in JK-1 and Enthalpy is measured in Jmol-1
