Entropy [ENDORSED]

[Tiffany Cao 1D]

When a system is heated, experiences an increase an volume, or a decrease in pressure, entropy increases. In what other scenarios will entropy increase?

[Naomi Jennings 2H]

When the system goes from solid to liquid, or liquid to gas, entropy also increases. If a reaction creates more mols of gas than were previously present then entropy increases as well.

[Mitch Walters]

Any reaction that has a negative delta G.

[Paula Dowdell 1F]

it's good to note that the entropy of a system decreases only when it interacts with some other system whose entropy increases in the process.

[Phi Phi Do 2E]

Entropy can increase when molecules are broken down.

[Dang Lam]

can you elaborate on why entropy increases when molecules are broken down please?
