Radiation, convection, conduction

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 heat through liquids and gases caused by the movement of the fluid itself. Hot fluid rises while cooler fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation. It does not require a medium to travel through.

Front

How does heat transfer when you touch a hot stove?

Back

Heat is transferred by conduction when you touch a hot stove, as thermal energy moves from the stove to your skin.

Front

What happens to water when it is heated on a stove?

Back

When water is heated, convection currents form as hot water rises and cooler water sinks, distributing heat throughout the pot.

Front

What is an example of conduction in everyday life?

Back

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

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

What is an example of radiation in everyday life?

Back

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

Front

What type of heat transfer occurs in a boiling pot of water?

Back

Convection occurs in a boiling pot of water as hot water rises and cooler water moves down.

Front

What is the primary way heat travels through solids?

Back

The primary way heat travels through solids is conduction.
