Conduction, Convection, & Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat energy is passed from one molecule to another.

Front

Give an example of conduction in everyday life.

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

How does convection work in boiling water?

Back

In boiling water, hot water at the bottom rises to the top, while cooler water descends, creating a circular motion that transfers heat.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

How does the Sun's heat reach the Earth?

Back

The Sun's heat reaches the Earth through radiation, as electromagnetic waves travel through the vacuum of space.

Front

What is an example of radiation in nature?

Back

An example of radiation in nature is the warmth felt from sunlight on your skin.

Front

What role does conduction play in melting ice on a warm surface?

Back

Conduction transfers heat from the warm surface to the ice, causing it to melt.

Front

Explain how solar radiation can affect temperature on Earth.

Back

Solar radiation heats the Earth's surface, which in turn warms the air above it, affecting weather and climate.

Front

What is the difference between conduction and convection?

Back

Conduction involves heat transfer through direct contact, while convection involves heat transfer through the movement of fluids.
