Thermal Energy Review

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

What is a conductor?

Back

A conductor is a material that allows heat or electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to flow through it easily. Examples include wood, plastic, and rubber.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, when you touch a hot stove, heat transfers from the stove to your hand.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). For example, warm air rising and cool air sinking creates a convection current.

Front

What is radiation?

Back

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

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does heat travel?

Back

Heat always travels from hot objects to cold objects until thermal equilibrium is reached.

Front

What are the three types of heat transfer?

Back

The three types of heat transfer are conduction, convection, and radiation.

Front

What happens to particles in a hot object?

Back

In a hot object, particles move faster and have more kinetic energy compared to particles in a cooler object.
