Thermal Energy

Thermal Energy can be transferred from one substance to another when they both have different temperatures. Thermal Energy ALWAYS goes from HOT to COLD. Warm things always transfer Thermal Energy to cool things, causing the lower temperature to rise. Thermal Energy will continue to transfer between the two substances until both of them reach the same temperature.

Conductor and Insulator

A conductor is an object that directs the performance and where Thermal Energy is transferred easily. ( example; Metal) An Insulator is a thing or substance that is used for insulation, and a material that poorly transfers energy. It takes longer to transfer energy because the insulator is poor. ( example; wood)

Conduction

The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature between adjoining regions, without movement of material.

Convection

The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity which results transfer of heat.

Radiation

Radiation is energy that comes from a source and travels through some material or through space. Light, heat and sound are types of radiation.
