Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when faster-moving particles collide with slower-moving ones, transferring energy.

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern.

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium, so it can occur in a vacuum, like the heat from the sun.

How does heat transfer occur in a metal spoon placed in hot soup?

Back

Heat transfer occurs through conduction, as the heat from the soup warms the spoon directly.

Front

What happens to warm air in a room?

Back

Warm air rises because it is less dense than cooler air, demonstrating convection.

What is an example of radiation in everyday life?

Back

An example of radiation is feeling warmth from a fire or a lamp without direct contact.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

What is an example of convection?

Back

An example of convection is boiling water, where hot water rises to the top and cooler water sinks.

What is the role of insulation in heat transfer?

Back

Insulation reduces heat transfer by conduction, convection, and radiation, keeping heat in or out of a space.

How does the pavement cook an egg on a hot day?

Back

The pavement conducts heat from the sun and transfers it to the egg, cooking it.
