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

Explanation:

Internal energy is the sum of the kinetic and potential energies of the particles in a substance. When the average kinetic energy of the particles (which make up the substance) increases, the internal energy (since kinetic energy is a part of internal energy) increases. Thermal energy is the part of internal energy that is related to the temperature (and movement of particles), so when internal energy increases (due to increased kinetic energy), thermal energy also increases. Temperature is a measure of the average kinetic energy of the particles. So when thermal energy (which is related to the motion of particles) increases, the temperature (which reflects the average kinetic energy of particles) increases.

Answer:

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 increases.
