Energy, entropy and change

Combustion releases energy to the surroundings; at constant pressure this is described by a negative enthalpy change.

Zinātne paliek atmiņā, ja definīcija ir saistīta ar kaut ko izmērāmu vai novērojamu.

Mixing two gases usually increases the number of accessible microscopic arrangements and therefore increases entropy.

At constant temperature and pressure, ΔG combines enthalpy and entropy to indicate thermodynamic spontaneity.
