Thermal Energy & the Kinetic Molecular Theory

Conduction → Transfer of thermal energy by collisions between particles in matter. Occurs in solids, liquids, & gases. Metals are the best conductors.

Convection → Transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place. Occurs in liquids & gases.

Radiation → Transfer of energy by electromagnetic waves. Occurs in gases only.

Transfer of thermal energy that occurs in solids, liquids, and gases when two substances of different temperatures touch.

Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, more dense fluids.

The transfer of energy by the movement of electromagnetic waves or subatomic particles.

A substance that allows the flow of electrical charge or transfers thermal energy through matter.

A material that does not conduct heat or electric current

Kinetic Molecular Theory | with Teacher Dan

Kinetic Molecular Theory

1. Gases are composed of tiny particles.

2. There are no attractive forces between molecules.

3. Gas molecules are always in constant random motion.

4. The molecules collide classically with container walls and one another.

5. The movement of gas molecules is affected by temperature. The average kinetic energy of the molecules is directly related to the temperature of a gas.
