What is heat?

way a hot-water radiator heats a room's air
A radiator uses conduction and convection to heat a room. Hot water moves through the inside of the radiator. Heat is transferred to the metal in the radiator, which is an example of conduction. The warm metal in the radiator transfers heat to nearby air particles in the room, and they move faster and rise upward. This allows cooler air to touch the hot metal of the radiator so heat can be transferred. Convection currents move the air through the room.
the transfer of heat that occurs when one thing touches another; example: When you boil water in a metal pan, the pan transfers heat to the water
it forms when gas or liquid transfers heat as it moves
why ice might melt after you skated on it
Skating on ice causes friction between the skates and the ice. Friction gives off heat, so the friction between the ice and the skates may give off enough heat to melt the ice.
energy that is sent out in waves; example: heat transferred from a campfire to the people around the campfire
the transfer of heat as matter moves; it involves a GAS or LIQUID moving from place to place; example: a mobile turns from a candle burning below it
