What does temperature measure the empty space between the particles the total energy of the particles the average kinetic energy of the particles the heat of the particles

Temperature measures the average kinetic energy of the particles in a substance.

Temperature is a measure of the average kinetic energy of the particles in a substance. It is related to the motion of particles; higher temperature implies that the particles are moving faster on average, while lower temperature implies slower average particle motion. Temperature itself does not measure the empty space between particles, the total energy of the particles, or the heat of the particles, but it is a quantitative measure of the average kinetic energy.
