Conduction, Convection & Radiation Practice

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 through physical touch.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense areas of a fluid rise and cooler, denser areas sink, 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.

Front

Which materials are good conductors of heat?

Back

Good conductors of heat include metals like copper, aluminum, and iron. They allow heat to pass through them easily.

Front

Which material is a poor conductor of heat?

Back

Plastic is a poor conductor of heat, meaning it does not transfer heat well.

Front

How does heat transfer in the ocean create currents?

Back

Heat transfer in the ocean creates currents primarily through convection, as warm water rises and cool water sinks.

Front

What role does convection play in weather systems?

Back

Convection is responsible for the circulation of heat in the atmosphere, which drives weather systems and patterns.

Front

How does an iron smooth out wrinkles in clothes?

Back

An iron smooths out wrinkles by transferring heat to the clothes through conduction, as the hot surface of the iron comes into direct contact with the fabric.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin, which occurs even though the sun is millions of miles away.

Front

What happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises, creating convection currents that can lead to wind and weather changes.
