Answer to Question #58213 in Physical Chemistry for GLORY
- Individual gas molecules are relatively far apart.
- The actual volume of the gas molecules themselves is very small compared to the volume occupied by the gas at ordinary temperatures and pressures.
- The average kinetic energies of different gases are different at the same temperature.
- There is no net gain or loss of the total kinetic (translational) energy in collisions between gas molecules.
The following statement “The average kinetic energies of different gases are different at the same temperature.” is not consistent with the kinetic-molecular theory of gases. The right statement should be “The average kinetic energy is the same for all gases at a given temperature, regardless of the identity of the gas.”
