Heat transfer

Front

What are materials that are good insulators?

Back

Materials like wood, straw, and wool are good insulators as they prevent heat transfer.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves, such as when the sun heats your body.

Front

What are materials that are good conductors?

Back

Materials like silver, stainless steel, and copper are good conductors as they allow heat to flow easily.

Front

What is an insulator?

Back

An insulator is a material that prevents or slows down the transfer of heat.

Front

What is convection?

Back

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

Front

How does heat transfer occur in liquids?

Back

In liquids, heat transfer occurs mainly through convection, where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is an example of conduction?

Back

An example of conduction is when a person touches a hot pot with bare hands, causing heat to transfer from the pot to the skin.

Front

What is an example of radiation?

Back

An example of radiation is feeling warmth from the sun on your skin, even when you are not in direct contact with it.

Front

What is the role of conductors in heat transfer?

Back

Conductors facilitate heat transfer by allowing thermal energy to move quickly through them.
