Front

What is thermal energy transfer?

Back

The movement of heat from one object or substance to another.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

The transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

The transfer of thermal energy through electromagnetic waves, such as sunlight.

Front

How does the sun transfer energy to the Earth?

Back

Through radiation.

Front

What happens to air in a hot air balloon?

Back

The air inside the balloon heats up, becomes less dense, and rises due to convection.

Front

How does a microwave heat food?

Back

By using radiation to excite water molecules in the food, causing them to heat up.

Front

What role does a radiator play in heating a room?

Back

It radiates heat into the room, warming the air and surfaces.

Front

How does a greenhouse maintain warmth?

Back

It uses radiation from sunlight to warm the air inside, and convection helps distribute the heat.

Front

What is an example of conduction in everyday life?

Back

Touching a hot stove and feeling the heat transfer to your hand.
