The temperature change between the two systems is the same in magnitude.


The energy transfer between the two systems is the same in magnitude but opposite in sign.


Even though energy is lost to the surroundings, the overall energy of the system is conserved.


The average kinetic energy of the two systems is generally higher than the average kinetic energy of either system individually.
