Heat Transfer

materials that are poor carriers of heat or electric current.

materials that easily carry heat or electric current.

heat energy moves through space from an area of higher temperature to an area of cooler temperature.

transfer of energy through space without particles of matter colliding or moving to transfer the energy.

This radiated energy warms an object when it is absorbed.

the transfer of energy as heat by movement of the heated substance itself, as currents in fluids (liquids and gases).

ocean currents

Heat transfer occurs when particles with higher energy move from warmer to cooler parts of the fluid.

Uneven heating both in the air and in water. This causes currents in the atmosphere (wind) and in bodies of water on earth which are important factors in weather and climate.

The transfer of energy as heat occurs between particles as they collide within a substance or between two objects in contact.

Poor conductors of heat .

The energy transfers from an area of higher temperature to an area of lower temperature through direct contact

The heat from sun heats the earth

materials that easily carry heat or electric current.

For example, if a plastic spoon and a metal spoon are placed into a hot liquid, the handle of the metal spoon will get hot quicker than the handle of the plastic spoon because the heat is conducted through the metal spoon better than through the plastic spoon.
