Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves. It does not require a medium and can occur in a vacuum.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot after being placed in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is the warm air rising from a heater, causing cooler air to move in and create a circulation of air.

Front

What is an example of radiation?

Back

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

Front

What is insulation?

Back

Insulation is a material that reduces the transfer of heat. It is not a method of heat transfer but rather a way to prevent heat loss.

Front

How does conduction occur in solids?

Back

In solids, conduction occurs as particles vibrate and collide with neighboring particles, transferring energy.

Front

How does convection occur in liquids?

Back

In liquids, convection occurs as warmer liquid rises and cooler liquid sinks, creating a current.

Front

How does radiation travel?

Back

Radiation travels in the form of electromagnetic waves, such as infrared radiation from a heat source.
