Heat conduction Facts for Kids

Heat conduction (or thermal conduction) is the movement of heat from one solid to another one that has different temperature when they are touching each other For example, we can warm our hands by touching hot-water bottl When the cold hands touch the hot-water bottle, heat flows from the hotter object (hot-water bottle) to the colder one (hand)...

heat - Students | Britannica Kids | Homework Help

Heat is the transfer of thermal energy from a hotter substance to a colder one Transferring heat to a substance usually raises its temperature In nearly all cases, matter increases in volume when there is an increase in temperature In gases the increase is a large one As the molecules that make up the gas begin speeding up, they also begin ....
