Front

What are the three kinds of heat transfer?

Back

Conduction, Convection, Radiation.

Front

How does heat energy reach the Earth from the Sun?

Back

Through Radiation.

Front

What is an example of convection?

Back

Movements of water in a pot, molten mantle in the earth's crust, and hot air rising in the atmosphere.

Front

What is the definition of conduction?

Back

When heat transfers from objects that are touching.

Front

In which direction does heat transfer?

Back

From an area of high temperature to an area of low temperature.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a hot soup.

Front

What happens to air when it is heated?

Back

It expands, becomes less dense, and rises.

Front

What is the role of insulation in thermal transfer?

Back

It reduces heat transfer between objects.
