Conduction Convection Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when molecules collide and transfer energy to neighboring molecules.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern.

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.

How does an iron smooth out wrinkles in clothes?

Back

An iron smooths out wrinkles by transferring heat to the clothes through conduction.

Front

How do heat lamps keep baby chickens warm?

Back

Heat lamps keep baby chickens warm by transferring heat through radiation.

Front

Why is the air warmer near the ceiling of a room?

Back

The air is warmer near the ceiling because warm air rises due to convection.

Front

What is the main way heat is transferred in a microwave?

Back

The main way heat is transferred in a microwave is through radiation.

Front

What causes sunburn?

Back

Sunburn is caused by radiation from the sun.

Front

Give an example of conduction in everyday life.

Back

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

Front

Give an example of convection in everyday life.

Back

An example of convection is boiling water, where hot water rises to the top and cooler water sinks.
