conduction,convection,radiation flashcard

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warm fluid rises and cool fluid sinks.

Front

What is radiation?

Back

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

Front

Why is copper commonly used in electrical wiring?

Back

Copper is an excellent electrical conductor, allowing electricity to flow easily.

Front

What is the best conductor of heat and electricity?

Back

Metals are generally the best conductors of heat and electricity.

Front

What happens to air when it is heated?

Back

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

Front

What type of energy is involved in heating water on a stove?

Back

Thermal energy is involved when heating water on a stove.

Front

How does the Sun heat the Earth?

Back

The Sun heats the Earth through radiation, emitting energy that travels through space.

Front

What is the difference between conduction and convection?

Back

Conduction involves heat transfer through direct contact in solids, while convection involves heat transfer through fluid movement.

Front

What role does insulation play in heat transfer?

Back

Insulation reduces heat transfer by conduction, convection, and radiation, helping to maintain temperature.
