Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, which is related to its temperature.

Front

How do particles in cold water move?

Back

Particles in cold water move with less energy and slowly.

Front

What are liquids and gases made up of?

Back

Liquids and gases are made up of particles of matter.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What happens when you add ice to water?

Back

Heat transfers out of the water into the ice, reducing the temperature of the water.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light.

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 difference between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature is a measure of the average kinetic energy of particles.
