Is the total random kinetic energy of particles in an object Which has more thermal energy? Why? A.Glass of water B.Lake Acworth

Is a flow of energy from an object at a higher temperature to an object at a lower temperature Heat is the result of molecules vibrating quickly. Heat is moving energy. What happens when you add heat energy to a pot of water?

The transfer of heat by direct contact between objects or particles.

Heat transferred through space. EXAMPLE: The sun’s rays causing a sunburn.

Heat transferred by the movement of molecules within a substance (liquids or gases). Movement occurs from warmer areas to cooler areas.

The movement of a substance that is caused by differences in temperature and density. EXAMPLES: wind boiling water NATURE WANTS EVERYTHING TO BALANCE !!

Conductors are materials that transfer heat easily. Examples: metals like copper and gold

An insulator is a material that does not transfer heat easily. Examples: liquids and gases A jacket
