Heat and materials

Front

What are insulators?

Back

Materials that do NOT transfer heat well or absorb heat, such as wood and air.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) due to differences in density.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

How does warm air behave compared to cold air?

Back

Warm air is less dense than cold air and rises, creating convection currents.

Front

What is a conductor?

Back

Materials that transfer heat well, such as metals.

Front

Give an example of conduction in everyday life.

Back

Grabbing a hot pot handle.

Front

Give an example of convection in everyday life.

Back

Boiling water where hot water rises and cold water sinks.

Front

Give an example of radiation in everyday life.

Back

Feeling the warmth of the sun on your skin.

Front

What happens to air when it is heated?

Back

It expands, becomes less dense, and rises.
