Temperature and Kinetic Energy

The atoms and molecules in a gas are in constant motion. Temperature is a measure of the speed with which they move. (More exactly it is a measure of their kinetic energy.) The higher the temperature, the faster the molecules move.


The simulation at right shows an ensemble of identical atoms or molecules in a closed container. You can change the temperature of the gas using the scrollbar.

Move the scrollbar and see the effect that changes in temperature have on the kinetic energy of the atoms or molecules.
