HELP PLEASE Temperature is a measure of the kinetic energies of the particles in a substance. However, because the particles in a substance move at different speeds, the particles can have different amounts of kinetic energy. So, what does temperature actually measure?

Temperature measures the average kinetic energy of the particles in a substance. When the particles in a substance have a higher average kinetic energy, the substance has a higher temperature.

Imagine a substance made up of 1,000 particles. Which of these describes the average kinetic energy of the particles?

A. the kinetic energy of the fastest particle multiplied by 1,000
B. the total kinetic energy of the particles plus 1,000
C. the sum of the particles kinetic energies divided by 1000
