# Difference between enthalpy and entropy

## The Mechanical engineering, is plays very crucial field in today's Technology that Assist you to do much things with ease, so let's learn about Concept Difference between enthalpy and entropy that would helps to standardize our society. (adsbygoogle = window.adsbygoogle || []).push({}); So keeping these things in mind, Lets learn the Difference between enthalpy and entropy .

 Difference between enthalpy and entropy

# Difference between enthalpy and entropy:-

#### Entropy

1.

Enthalpy is defined as the sum of total internal energy and the product of pressure and change in volume.

Entropy is defined as the randomness of molecular system or molecular disorderness.

2.

Enthalpy represent the kind of energy of system.

Entropy represent the property of system.

3.

The term enthalpy explained by the scientist of heike kamerlingh onnes.

The term entropy explained by the scientist of Rudolf clausius.

4.

Enthalpy is denoted by the letter, H

Entropy is denoted by the letter, S

5.

The unit of enthalpy is, J/mol .

The unit of entropy is, J/K.

6.

The system can be approching minimum enthalpy.

The system can be approching maximum entropy.

7.

Enthalpy of universes not always increases.

Entropy of universe is always increases.

8.

The enthalpy works on constant pressure process.

The entropy works on constant temperature process.

9.

For isolation system enthalpy is zero.

For isolation system entropy is always increases.

10.

Enthalpy follows first law of thermodynamics.

Entropy follows second law of thermodynamics.

11.

The application of enthalpy is in  limit or in standard condition.

The application of entropy is limitless or not in standard condition.

12.

Mathematically,

Enthalpy is,

H = U + PdV

Mathematically,

Entropy is,

S = T dS

13.

Application:-

The concept of enthalpy used in fridge, refrigerator, hand wormer etc.

Application:-

The concept of entropy used in ice melting, sugar dissolving, water boiling etc.
