WebMay 13, 2024 · For gases, there are two possible ways to evaluate the change in entropy. We begin by using the first law of thermodynamics: dE = dQ - dW. where E is the internal … WebIn accordance with the formula G = H-TS, the molar surface entropy Sms of nano-CaMoO 4 can be obtained as: S m s = ( H m s − G m s) / T. (12) Thus, the molar surface enthalpy, molar surface Gibbs free energy, and molar surface entropy of nano CaMoO 4 can be acquired from Equations (6), (11) and (12), respectively. 5. medicated hand cream for cracked hands
