Question

What is transfer of heat. Describe the 3 processes you studied by which heat can be transferred. Give examples also.
​

Answer 1

Answer:

The three types of heat transfer

Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own.

Answer 2

Answer:

heat transfer happens partly because of either the actual movement of molecules or due to the mass transfer.

Explanation:

In a fireplace, heat transfer occurs by all three methods: conduction, convection, and radiation. Radiation is responsible for most of the heat transferred into the room. Heat transfer also occurs through conduction into the room, but at a much slower rate.

One of the modes of heat transfer examples is Heating milk in a pan.
