CONDUCTION,CONVECTION AND RADIATION

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) where hot fluid rises and cooler fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of energy through waves or rays, such as heat from the sun.

Front

Example of conduction?

Back

A hot biscuit warming the plate it is on.

Front

Example of convection?

Back

Boiling water where hot water rises and cooler water sinks.

Front

Example of radiation?

Back

The sun shining through a window and warming a table.

Front

What is the original source of most energy used on Earth?

Back

Energy that reaches Earth by radiation from the sun.

Front

How does heat transfer through conduction occur?

Back

Heat transfers when two objects at different temperatures are in direct contact.

Front

How does convection work in the atmosphere?

Back

Warm air rises, cools down, and then sinks, creating a convection current.

Front

What is an example of convection in everyday life?

Back

Heating a room with a radiator.
