Heat & Temperature

Front

What is radiation?

Back

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

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.

What is conduction?

Back

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

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object. It depends on the temperature and the number of particles.

What is an example of radiation?

Back

An example of radiation is feeling warmth from the sun or a fireplace without direct contact.

Front

What is an example of convection?

Back

An example of convection is warm air rising near a heater, causing cooler air to move in and create a circulation.

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

What happens to air when it is heated?

Back

When air is heated, it expands, becomes less dense, and rises, leading to convection currents.
