WebDec 23, 2024 · How does heat move through the air without touching it? If you lean over a radiator without touching it, you can feel hot air rising. This is called convection, and it is the main way heat travels through liquids and gases. Heat can also travel as invisible waves through the air or empty space. This is called radiation. Which is the method of ... WebConvection is how heat travels through fluids – liquids and gases. Hot fluids rise up, while cold fluids sink down. This up-and-down motion is called a convection current. Convection current spreads the heat in a circular, up-and-down pattern. Radiation is how heat travels through empty space. Radiation does NOT require molecules to travel ... WebThis process of transfer of heat in liquids is called convection. Small Activity on Transfer of Heat in Gases Light a candle and place it on a stand. Now, place one hand above the flame (at a safe distance so that you don’t burn your hand) and the other at the side of the flame. Do both the hands feel equally hot? No. phi theta psi
