What is heat always moves from hot to cold?Show answer
Heat energy always flows from a hotter place to a cooler place. It keeps flowing until both places are at the same temperature. There are three ways this can happen.
What is conduction?Show answer
Conduction is how heat travels through solids, especially metals.
What is convection?Show answer
Convection is how heat travels through liquids and gases (fluids).
What is radiation?Show answer
Radiation is how heat travels as invisible waves, called infrared radiation. It is the only way that does not need any particles, so it can travel through empty space.
