Question

Complete the passage to describe the relationship between kinetic energy, internal energy, thermal energy, and temperature.

As the average kinetic energy of a substance increases, the internal energy
, and so its thermal energy
. As the thermal energy of a substance increases, the temperature

Answer 1

As the average kinetic energy of a substance increases, the internal energy increases, and so its thermal energy increases. As the thermal energy of a substance increases, the temperature usually increases (unless the added energy is used for a phase change), because temperature measures the average kinetic energy of the particles.
