WebFeb 22, 2024 · Gases have higher entropy than liquids, which have higher entropy than solids. This is prioritized and the most important. If the substances are in the same state, however, their complexity does matter, like you said - # of atoms, #of bonds, even # of electrons, potentially. WebThe average kinetic energy for a mole of particles, KE avg, is then equal to: KE avg = 1 2 M u rms 2. where M is the molar mass expressed in units of kg/mol. The KE avg of a mole of gas molecules is also directly proportional to the temperature of the gas and may be described by the equation: KE avg = 3 2 R T.
