When the particles in a substance slow down, here's what happens to the average kinetic energy, thermal energy, and temperature:
1. Average Kinetic Energy:
- The average kinetic energy of the particles decreases because kinetic energy is related to the speed of the particles. Slower particles have lower kinetic energy.
2. Thermal Energy:
- The thermal energy of the substance also decreases as the particles slow down because thermal energy is the total kinetic energy of all the particles in a substance. If the particles are moving slower, the total kinetic energy (thermal energy) decreases.
3. Temperature:
- The temperature of the substance decreases as the particles slow down. Temperature is a measure of the average kinetic energy of the particles. Since the average kinetic energy decreases when the particles slow down, the temperature also decreases.
In summary, when the particles in a substance slow down, the average kinetic energy, thermal energy, and temperature of the substance all decrease.
