Heat transfer-Conduction Convection Radiation

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, like when a metal spoon gets hot from being in a pot of boiling water.

What is convection?

Back

Convection is the transfer of heat through liquids and gases. It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks, creating a circulation pattern, like warm air rising near the ceiling of a room.

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves. It does not require a medium to travel through, which is why we can feel the heat from the sun even though space is a vacuum.

How does heat travel through solids?

Back

Heat travels through solids primarily by conduction, where heat is transferred through direct contact between particles.

Front

How does heat travel through liquids and gases?

Back

Heat travels through liquids and gases primarily by convection, where warmer areas of fluid rise and cooler areas sink.

Front

What happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises, leading to convection currents.

What is an example of conduction in everyday life?

Back

An example of conduction is when you touch a hot stove and feel the heat transfer to your hand.

What role does conduction play in cooking?

Back

Conduction allows heat to transfer from the stove to the pot, cooking the food inside.
