PS3-3 Thermal Energy Review

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object, which is related to its temperature.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials, without the movement of matter.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as light, without the need for a medium.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of thermal energy, helping to keep heat in or out.

Front

What is a good example of a thermal insulator in a house?

Back

Insulation in drywall is a good example of a thermal insulator.

Front

What is a good example of a radiation insulator?

Back

Aluminum is a good example of a radiation insulator.

Front

How does temperature relate to thermal energy?

Back

Temperature measures the average kinetic energy of particles, while thermal energy measures the total kinetic energy of all particles in an object.

Front

What happens to thermal energy when an object is heated?

Back

When an object is heated, its thermal energy increases, causing its particles to move faster.

Front

What is the difference between thermal energy and temperature?

Back

Thermal energy is the total energy of all particles in an object, while temperature is a measure of the average energy of those particles.
