Front

What is the main characteristic of convection currents?

Back

They involve the movement of fluids (liquids or gases) due to temperature differences.

Front

What happens to the particles in a substance when it is heated?

Back

They gain energy and move faster.

Front

What is the role of insulation in heat transfer?

Back

It reduces heat transfer by conduction, convection, and radiation.
