Heat Transfer: 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). It occurs when warmer, less dense areas of a fluid rise and cooler, denser areas sink.

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through space.

How does a spoon get hot when stirring hot coffee?

Back

The spoon gets hot due to conduction, as heat is transferred from the hot coffee to the spoon through direct contact.

Front

What happens to warm air in a room?

Back

Warm air rises because it is less dense than cooler air, leading to convection currents in the room.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is holding an ice cube in your hand; the heat from your hand melts the ice.

What is an example of convection in action?

Back

An example of convection is the way warm air rises from a heater, creating a circulation of air in the room.

Front

What is an example of radiation?

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 is the role of insulation in heat transfer?

Back

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

How does heat transfer affect weather patterns?

Back

Heat transfer through convection in the atmosphere contributes to weather patterns, such as wind and storms.
