# Difference Between Enthalpy and Entropy

We know that the major difference between enthalpy and entropy is that even though they are part of a thermodynamic system, enthalpy is represented as the total heat content whereas entropy is the degree of disorder.

In a closed system, $T.\Delta S=\Delta H$, which means that in absolute temperature with some change in entropy results in a change of enthalpy.

## Difference Between Enthalpy and Entropy

Enthalpy is the measure of total heat present in the thermodynamic system where the pressure is constant.

It is represented as $\Delta H=\Delta E+P\Delta V$ where E is the internal energy.

Entropy is the measure of disorder in a thermodynamic system. It is represented as $\Delta S=\Delta Q/T$ where Q is the heat content and T is the temperature.

Difference Between Enthalpy and Entropy
