Heat Transfer Practice

Front

What is conduction?

Back

Conduction is the transfer of heat energy from one place to another through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of currents in liquids or gases.

Front

What is radiation?

Back

Radiation is the transfer of heat energy through electromagnetic waves, without the need for a medium.

Front

How does heat flow between two objects?

Back

Heat always flows from an area of high temperature to an area of low temperature.

Front

What happens when you touch a hot object?

Back

You experience conduction, as heat transfers from the hot object to your skin.

Front

What is an example of convection?

Back

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

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What is the role of particles in conduction?

Back

In conduction, particles vibrate and transfer energy to neighboring particles through direct contact.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is a real-life example of convection?

Back

A real-life example of convection is the heating of air in a room by a radiator.
