What is enthalpy What is entrophy

Question

Accepted Answer

Enthalpy is the total heat content of a system, including internal energy and pressure-volume work. Entropy is a measure of disorder or randomness in a system.

Enthalpy is represented by the symbol H and is defined as H = U + PV, where U is the internal energy, P is the pressure, and V is the volume.
Entropy is represented by the symbol S and is a measure of the amount of energy in a system that is unavailable to do work.
Enthalpy is often used in thermodynamics to analyze energy changes in chemical reactions, while entropy is used to describe the direction of spontaneous processes.
An example of enthalpy is the heat absorbed or released during a chemical reaction, while an example of entropy is the mixing of hot and cold water resulting in a temperature equilibrium.
Enthalpy is a state function, meaning it depends only on the initial and final states of a system, while entropy is a measure of the number of possible arrangements of particles in a system.
