What is the relationship between thermal energy, kinetic energy, particle movement and temperature?
Temperature, thermal energy and kinetic energy increase when particle movement slows down.
Then the particles start to move the thermal and kinetic energy decreases and so does the temperature.
When the temperature decreases thermal and kneticenergy increase and particle movement increase.
When the temperature increases, thermal and kinetic energy increase and particle movement increase.
