Heat Transfer

Front

What is the relationship between molecular motion and temperature?

Back

The quicker a molecule moves, the warmer it is.

Front

What type of heat transfer occurs when a house burns down and affects nearby structures?

Back

Radiation.

Front

What is the primary method of heat transfer from the sun to the Earth?

Back

Radiation.

Front

What causes warm air to rise and cooler air to rush in at the beach?

Back

Convection.

Front

What is an example of convection in everyday life?

Back

When you are making soup and the water is rising and lowering.

Front

Define conduction in the context of heat transfer.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection and how does it occur?

Back

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

Front

Explain the process of radiation in heat transfer.

Back

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

Front

What is the role of density in convection currents?

Back

Density differences in fluids cause warmer, less dense fluid to rise and cooler, denser fluid to sink, creating convection currents.

Front

How does the sun's energy reach the Earth?

Back

The sun's energy reaches the Earth primarily through radiation.
