Heat Transfer

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). Warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern.

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 empty space.

Front

Give an example of convection.

Back

An example of convection is the movement of warm air rising to the ceiling in a room, causing cooler air to sink.

Front

Give 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.

What happens to the temperature of a sidewalk on a sunny day?

Back

The sidewalk increases in temperature due to radiation from the sun.

How does heat transfer occur when you touch a hot stove?

Back

Heat transfer occurs through conduction when you touch a hot stove, causing your hand to burn.

Front

What is the role of density in convection?

Back

In convection, warmer fluids are less dense and rise, while cooler fluids are denser and sink, creating a cycle of movement.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.
