Thermal Energy

Temperature is...

• the total energy of all particles in a substance

• the measure of kinetic particles in a substance

• the movement of thermal energy from warmer objects to cooler objects

• Heat transfer in all forms

This type of thermal energy transfer can take place in solids, liquids, & gases when two objects are touching.

• conduction

• convection

• radiation

This type of thermal energy transfer can take place in fluids (liquids & gases). Rising of warmer fluid and sinking of cooler fluid forms a current.

Conduction

• The transfer of energy by electromagnetic waves.

• A circular motion of air that causes wind and changes in weather

• A type of heat transfer that occurs through the movement of fluids.

• The transfer of energy from one particle of matter to another within an object or between two objects that are in direct contact.
