What is entropy? Give its units.

2nd Law of Thermodynamic

Second Law OF Thermodynamics, Entropy and its Calculation

Entropy | Third law of thermodynamics

Statement -1: Entropy change in reversible adiabatic expansion of an ideal gas is zero. Statement-2: The increase in entropy due to volume increase just compensates the decrease in entropy due to fall in temperature.

Statement-1 : Entropy of all elements is zero at zero Kelvin. Statement-2 : Standard entropy of all elements is greater than zero. Statement-3 : Entropy of all elements and compounds decreases with decrease of temperature and becomes zero at absolute zero temperature.
