What is conduction?

Back

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

Front

What is convection?

Back

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

How does convection work in water currents?

Back

In water currents, warmer water rises and cooler water sinks, creating a circulation pattern that transfers heat from warmer to cooler areas.

What happens to thermal energy when a substance is heated?

Back

When a substance is heated, its particles gain kinetic energy, causing an increase in temperature and thermal energy.
