SUMMARY
At the triple point of water (273.16 K), the chemical potentials of ice, water, and vapor are equal, not the average kinetic energies of the particles. While temperature is defined as the average kinetic energy (KE) of particles, the mean squared speeds of molecules in different states (liquid and gas) can be the same at this temperature due to the relationship defined by the equation KE = 3/2 kT. This indicates that the translational mean squared speeds of water and vapor can be equal at the same temperature, despite differences in their states.
