Question

How does heat travelled in air?

Answer 1

Answer:

Heat travels in air through convection. Smoke goes up in the air because hot air is lighter than cool air.

Answer 2

Answer:

Heat moves in three ways, conduction convection, and radiation. Heat travels in the air through convection.

Explanation:

Heat travels when things are at different temperatures, always moving from hotter to colder things. Smoke goes up in the air because hot air is lighter than cool air. When you touch something hot and you feel the heat moving in your body, it's called conduction which happens when hot things touch cooler ones. If you lean over a radiator, without touching it, you can feel hot air rising up, it's called convection which is the main way heat travels through liquids and gases. Heat can also travel through invisible waves through the air or empty space, it's called rediation.
