Question

What is convection?????
​

Answer 1

Answer:

Convection is the transfer of heat due to the bulk movement of molecules within fluids, including molten rock. Examples of Convection :

radiator - A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting - Ice melts because heat moves to the ice from the air.

Answer 2

Answer:

Convection is the process by which heat transfer takes place by the actual movement of molicules.

Explanation:

When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises.

➔Types of convection

1. Natural convection
2. Forced convection
