Heat transfer

Front

What is an insulator?

Back

An insulator is a material that prevents or slows down the transfer of heat. Examples include wood, straw, and wool.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials. An example is ironing a shirt.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. An example is the heat from the sun warming your body.

Front

What materials are good insulators?

Back

Materials like wood, straw, and wool are good insulators because they do not conduct heat well.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily. Metals like copper and aluminum are good conductors.

Front

How does heat transfer from the sun to the Earth?

Back

Heat transfer from the sun to the Earth occurs through radiation.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

What happens to the temperature of a substance during conduction?

Back

During conduction, the temperature of the substance can increase as heat is transferred from a hotter object to a cooler one.

Front

What is the role of heat lamps for baby chickens?

Back

Heat lamps provide radiation to keep baby chickens warm, demonstrating the principle of heat transfer through radiation.
