Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when particles collide with each other, transferring energy.

Front

Give an example of conduction.

Back

An example of conduction is a metal spoon heating up when placed in a bowl of hot soup.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It creates currents as warmer, less dense areas rise and cooler, denser areas sink.

Front

Give an example of convection.

Back

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

Front

What is radiation?

Back

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

Front

Give an example of radiation.

Back

An example of radiation is the heat from the sun warming the Earth.

Front

What type of heat transfer occurs in a microwave?

Back

The type of heat transfer that occurs in a microwave is radiation.

Front

What is thermal energy?

Back

Thermal energy is the energy an object has due to the motion of its particles; it is the total amount of kinetic energy of particles in an object.

Front

What creates currents in water?

Back

Currents in water are created by convection.

Front

How does heat transfer through conduction occur?

Back

Heat transfer through conduction occurs when particles in a material collide and transfer energy to neighboring particles.
