Thermal Energy Lesson 7-14 Review

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to their temperature and motion.

Front

What happens to particles in a solid?

Back

In a solid, particles are closely packed together and vibrate in place.

Front

What happens to particles in a liquid?

Back

In a liquid, particles are close together but can move around freely.

Front

What happens to particles in a gas?

Back

In a gas, particles are spread out and move freely, occupying more space.

Front

What is the process of heat transfer from one object to another?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What is the relationship between temperature and thermal energy?

Back

As temperature increases, the thermal energy of the particles in a substance also increases.

Front

What is the principle of heat transfer?

Back

Heat moves from areas of higher temperature to areas of lower temperature.

Front

What effect does light energy have on water?

Back

Light energy can increase the thermal energy of water, causing it to heat up.
