Define conduction in the context of heat transfer.

Back

Conduction is the transfer of heat through a solid material without any movement of the material itself.

What is convection and how does it occur?

Back

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

Front

Explain radiation as a method of heat transfer.

Back

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

Front

How does temperature affect the movement of molecules?

Back

As temperature increases, the movement of molecules becomes faster.

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat to each other because they are at the same temperature.

What role does the Sun play in heat transfer on Earth?

Back

The Sun transfers energy to Earth primarily through radiation.

Front

How does the density of a fluid affect convection currents?

Back

In convection, warmer, less dense fluid rises while cooler, denser fluid sinks, creating convection currents.
