definition of Enthalpy and entropy

Question

Accepted Answer

Enthalpy is the heat content of a system, while entropy is a measure of disorder or randomness.

Enthalpy is a thermodynamic property that accounts for the heat energy of a system.
It is represented by the symbol H and is measured in units of energy (e.g., joules).
Enthalpy change (∆H) is the difference in enthalpy between the products and reactants in a chemical reaction.
Entropy is a measure of the degree of randomness or disorder in a system.
It is represented by the symbol S and is measured in units of entropy (e.g., joules per kelvin).
Entropy change (∆S) is the difference in entropy between the products and reactants in a chemical reaction.
Enthalpy and entropy are related through the Gibbs free energy equation: ∆G = ∆H - T∆S, where ∆G is the change in Gibbs free energy, T is the temperature in Kelvin, and ∆S is the entropy change.
Enthalpy is often associated with heat transfer, while entropy is associated with the direction of spontaneous processes.
