Enthalpy and Entropy

Postby Ava Harvey 2B » Wed Jan 10, 2018 6:22 pm

Can someone please explain to me the difference between enthalpy and entropy, and if there's any relation between the two? Thanks so much!

Enthalpy is the sum of internal energy and is the amount of energy released or absorbed during a reaction. Entropy, however, is the measurement of the disorder of a system. I don't think that there is any direct relationship between the two. Hope this helps!

Enthalpy is the measurement of the sum of the internal energy and the product of the pressure and volume of a system. Entropy, on the other hand, is simply a measurement of disorder in the universe. Although we haven't covered it yet, the equation G = H - TS partially relates enthalpy H and entropy S in the measurement of G, or Gibbs free energy. T represents temperature.
