CONDUCTION,CONVECTION AND RADIATION

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation, and does not require a medium.

Front

How does temperature affect molecular movement?

Back

Higher temperature means faster moving molecules, as heat energy increases their kinetic energy.

What happens to a car's inside temperature on a sunny day?

Back

A car’s inside temperature rises to over 100 degrees due to radiation from the sun.

Front

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

Back

The original source of most energy that people use is energy that reaches Earth by radiation from the sun.

Front

How does a pot get hot on a stove?

Back

A pot gets hot on a stove due to conduction, as heat is transferred from the stove to the pot.

Front

What is an example of convection?

Back

An example of convection is when hot air rises and cool air sinks, creating a circulation pattern in a room.

Front

What is an example of conduction?

Back

An example of conduction is touching a metal spoon that has been sitting in a hot pot of soup; the heat transfers from the soup to the spoon.

Front

What is an example of radiation?

Back

An example of radiation is feeling warmth from the sun on your skin, even when you are not in direct contact with it.
