Entropy Changes

Postby Gabriel Ordonez 2K » Thu Feb 13, 2020 3:01 pm

How does entropy change with adjusting pressure, volume, temperature, heat, etc?

An increase in pressure causes a decrease in entropy. An increase in volume causes an increase in entropy. An increase in temperature causes an increase in entropy.

Also remember that entropy increases with the complexity of a molecule and also increasing molar mass. It also increases from solid to gas phases.

You can see how entropy increases with an increase in volume in the equation ∆S = nRln(V2/V1)
Similarly, entropy also increases with an increase in temperature in the equation ∆S = nCln(T2/T1)
