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 the 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 


Enthalpy 
Entropy 
Enthalpy is a kind of energy 
Entropy is a property 
It is the sum of internal energy and flow energy 
It is the measurement of randomness of molecules 
It is denoted by symbol H 
It is denoted by symbol S 
It was termed by a scientist named Heike Kamerlingh Onnes 
It was termed by a scientist named Rudolf Clausius 
It unit is \(Jmol^{1}\) 
It unit is \(JK^{1}\) 
It related is applicable in standard conditions 
It does not have any limits or conditions. 
The system favour minimum enthalpy 
The system favour maximum entropy
