Physics lesson (think4)

Thermal energy flows from a hotter region to a colder region until reach thermal equilibrium.

The greater the temperature difference, the faster the rate of transfer thermal energy.

Molecules are always moving at constant random motion.
Solid- only can vibrate at its position
Liquid- can move
Gases- moving faster
Molecules stop moving at absolute 0.
