What is the process of heat transfer through direct contact between materials?

Back

Conduction

Front

What is the primary method of heat transfer in fluids (liquids and gases) that involves the movement of the fluid itself?

Back

Convection

Front

What type of heat transfer does not require a medium and can occur in a vacuum?

Back

Radiation

Front

What is the term for the transfer of thermal energy from a warmer object to a cooler object through electromagnetic waves?

Back

Radiation

Front

In which type of heat transfer does warm air rise and cool air sink, creating a cycle?

Back

Convection

Front

What is an example of conduction in everyday life?

Back

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

Front

How does a microwave cook food?

Back

Through radiation, as it uses electromagnetic waves to heat the food.

Front

What is the role of insulation in a house regarding heat transfer?

Back

Insulation reduces conduction and convection, helping to maintain temperature.

Front

What is the main reason the sun warms the Earth?

Back

Radiation, as sunlight travels through space and heats the Earth's surface.

Front

What happens to the temperature of a substance when it absorbs thermal energy?

Back

The temperature increases as the kinetic energy of the particles increases.
