Heat & Heat Movement

Front

What is heat conduction?

Back

Heat conduction is the transfer of heat through a material without the movement of the material itself. It occurs more easily in solids because their particles are closer together.

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself. Warmer, less dense fluid rises while cooler, denser fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation. It does not require a medium to travel through.

Front

How does temperature affect particle movement?

Back

As temperature increases, particles move faster. In solids, they vibrate in place; in liquids and gases, they move more freely.

Front

What happens to heat when a hot object is placed in water?

Back

Heat from the hot object transfers to the water, causing the water temperature to rise.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is the role of insulation?

Back

Insulation reduces heat transfer between objects, helping to keep heat in or out, such as in buildings or coolers.

Front

What is the difference between conductors and insulators?

Back

Conductors are materials that allow heat to flow easily (e.g., metals), while insulators resist heat flow (e.g., wood, plastic).

Front

What is an example of heat transfer by radiation?

Back

An example of heat transfer by radiation is feeling the warmth of the sun on your skin.

Front

What is the process of heat transfer from the Earth's core to its crust?

Back

The main method of heat transfer from the Earth's core to its crust is convection.
