Entropy Calculator

Entropy (ΔS): -- J/K

What is this calculator used for?

This Entropy Calculator helps you determine the change in entropy (ΔS) during a thermodynamic process. It is especially useful in chemistry and physics for analyzing energy dispersal and system disorder.

How to use this calculator

  • Enter the amount of heat transferred in joules (Q).
  • Enter the temperature in kelvins (T).
  • The entropy change will be calculated automatically.

Formula

ΔS = Q / T

Where:

  • ΔS is the change in entropy (in joules per kelvin, J/K)
  • Q is the heat transferred (in joules)
  • T is the temperature (in kelvins)

Example

If 200 J of heat is transferred at a temperature of 300 K:

ΔS = 200 / 300 = 0.6667 J/K
