Entropy Calculator
Calculate thermodynamic entropy change for phase changes, heating, cooling and two-body mixing with heat, equilibrium temperature and total entropy output.
Thermodynamic entropy change
This tool is for thermodynamic entropy, not Shannon entropy. It estimates entropy change from reversible heat paths.
T must be absolute temperature in kelvins.
For heating or cooling with approximately constant heat capacity.
