Heat Transfer

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm 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. It does not require a medium to travel, allowing heat to be transferred through empty space.

Front

How does heat move between objects?

Back

Heat moves from a warmer object to a cooler object until thermal equilibrium is reached.

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 near 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 warmth from the sun on your skin, even though you are not in direct contact with it.

Front

What are the three types of heat transfer?

Back

The three types of heat transfer are conduction, convection, and radiation.

Front

What happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises, while cooler air moves down to take its place.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.
