Radiation, convection, conduction

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense areas of a fluid rise and cooler, denser areas sink.

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, allowing heat to be transferred through empty space.

Front

Which materials are good conductors of heat?

Back

Good conductors of heat include metals like copper, aluminum, and iron. They allow heat to pass through them easily.

Front

Which material is a poor conductor of heat?

Back

Plastic is a poor conductor of heat, meaning it does not transfer heat well.

Front

How does a hot spoon help scoop ice cream?

Back

The warmth of the spoon is conducted to the ice cream, making it easier to scoop out.

Front

What is an example of convection in everyday life?

Back

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

Front

What is an example of radiation?

Back

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

Front

What happens to the temperature of a substance during conduction?

Back

During conduction, the temperature of the hotter substance decreases while the cooler substance increases until they reach thermal equilibrium.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.
