Thermal Energy & Transforming Energy

Front

What is thermal energy?

Back

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

Front

What is the process of energy transfer through radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight warming your skin.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas rise and cooler areas sink.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, such as touching a hot stove.

Front

What is insulation?

Back

Insulation is a material that reduces the transfer of heat, helping to keep homes warm in winter and cool in summer.

Front

How does air act as an insulator?

Back

Air is a poor conductor of heat, so trapped air in materials like fiberglass slows down heat transfer.

Front

What happens to thermal energy when heat is added to an object?

Back

When heat is added, the thermal energy of the object increases, raising its temperature.

Front

What is the role of fiberglass in home insulation?

Back

Fiberglass slows the flow of energy, helping to keep homes warm by trapping air.

Front

How does temperature affect the movement of air?

Back

Warmer air is less dense and rises, while cooler air is denser and sinks, creating convection currents.

Front

What is the difference between thermal energy and temperature?

Back

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