Heat Transfer

Front

What is an insulator?

Back

An insulator is a material that prevents heat, electricity, sound, or light from passing through it.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves, such as when the sun warms your skin while sunbathing.

Front

What is convection?

Back

Convection is the transfer of heat in a fluid (gas or liquid) through the movement of the fluid itself, often seen in boiling water.

Front

What are convection currents?

Back

Convection currents are the up and down movements in a fluid caused by the transfer of heat, which helps distribute thermal energy.

Front

What is thermal energy?

Back

Thermal energy is the total energy of particles in a substance; more particles mean more energy.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, such as when a metal spoon gets hot in a pot of soup.

Front

What is a conductor?

Back

A conductor is a material that allows heat or electricity to pass through it easily, like metals.

Front

What is the difference between conduction and convection?

Back

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

Front

Can you give an example of conduction?

Back

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

Front

What is an example of convection in everyday life?

Back

An example of convection is the warm air rising from a heater and circulating in a room.
