Convection, Conduction, Radiation Practice

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through space without the need for a medium, such as air or water. An example is the sun warming your skin.

Front

What are the three types of heat transfer?

Back

The three types of heat transfer are conduction, convection, and radiation.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm air rises while cool air sinks, creating a circulation pattern.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. An example is a metal spoon getting hot when placed in a hot pot.

Front

What is an example of convection?

Back

Movements of water in a pot when heated, molten mantle in the earth's crust, and hot air rising in the atmosphere are all examples of convection.

Front

How does radiation differ from conduction and convection?

Back

Radiation does not require a medium to transfer heat, while conduction and convection do.

Front

What happens to warm air in convection?

Back

In convection, warm air rises because it is less dense than cool air, which then sinks.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is the role of convection in weather patterns?

Back

Convection plays a crucial role in weather patterns by causing warm air to rise and cool air to sink, leading to wind and cloud formation.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, which determines its temperature.
