Formula
DeltaS
the entropy change
n

P0
the initial pressure
R
ideal gas constant
Formula description
Entropy is a thermodynamic property that can be used to determine the energy available for useful work in a thermodynamic process, such as in energy conversion devices, engines, or machines. When specific heat and temperature are constant, the change in entropy is given by the formula.
