Key Concepts

Reversible Process

A reversible process is an idealized thermodynamic process that occurs infinitely slowly, allowing the system to remain in equilibrium at all stages. Such processes allow for the precise calculation of entropy changes using the relationship ?S = ?Q/T, where ?Q is the reversible heat transfer at constant temperature.

Latent Heat

Latent heat is the amount of energy absorbed or released by a substance during a phase change at a constant temperature and pressure. In the context of condensation, the latent heat of vaporization is released as the substance transitions from a gaseous to a liquid state, directly impacting the change in entropy.

Entropy

Entropy is a thermodynamic state function that quantifies the degree of disorder or randomness within a system. It is a central concept in the second law of thermodynamics, and changes in entropy are used to assess the feasibility and spontaneity of processes, especially in energy transformations.

Phase Transition

A phase transition refers to the change of a substance from one state of matter to another, such as from gas to liquid during condensation. During such transitions, even though the temperature remains constant, significant energy transfer occurs and is associated with a latent heat, which affects the entropy of the system.
