Front

Define conduction.

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself, typically occurring through direct contact between molecules.

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.

Explain radiation in the context of heat transfer.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum and does not require a medium.

How does warm air behave in a room?

Back

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

What happens to the temperature of water in a swimming pool?

Back

The water near the surface is warmer due to sunlight and rises, creating convection currents.

Front

What is the role of density in convection?

Back

Density differences in fluids cause warmer, less dense regions to rise and cooler, denser regions to sink, creating convection currents.

How does conduction occur in metals?

Back

In metals, conduction occurs as free electrons move and transfer kinetic energy to neighboring atoms.

What is an example of radiation in everyday life?

Back

An example of radiation is feeling warmth from the sun on your skin, even when standing in the shade.

Describe a real-world application of convection.

Back

A real-world application of convection is in heating systems, where warm air rises and circulates to heat a room.
