WebHeat moves through convection in gases, like air or steam, or liquids, for example in water. There are three ways of transferring heat: - conduction - when heat travels through direct contact between objects or substances, - radiation - when heat travels through space between different objects, - and convection - when heat flows within liquids ... WebThe visible sign of radiation is when you heat up a substance as much as you can, say, for example, heating a stove for a long time will make it glow red. This is a visible sign of radiation. However, even if it is visibly not glowing, then also it radiates heat.
