How do we differentiate entropy and enthalpy is a simple manner?

Entropy refers to the degree of disorder of a substance whereas enthalpy is a measure of the change in energy in a system. Enthalpy is the sum of the internal energy of a system and PxV. Entropy focuses more on how much the energy of atoms or molecules is spread over a certain process, it takes into account how close together particles are and therefore how many possible positions they can occupy over a certain volume.

Enthalpy is the amount of heat released or absorbed at a constant pressure, whereas entropy is a measure of disorder. Entropy deals with the state of a system, and the likelihood that the system will be in a particular state.
