Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object due to their movement and position.

Front

How do we measure temperature?

Back

Temperature is a way we measure thermal energy.

Front

What happens to the thermal energy of an object when its mass increases?

Back

Objects with more mass have higher thermal energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of movement.

Front

What happens to molecules in a substance when temperature increases?

Back

Molecules move more when temperature increases.

Front

Why are there joints in bridges?

Back

Joints allow the materials to expand without breaking when temperature increases.

Front

Which has the highest thermal energy: a hot cup of tea, cold bathtub water, a huge lake, or a warm bowl of soup?

Back

A huge lake has the highest thermal energy.

Front

What is the relationship between temperature and thermal energy?

Back

As temperature increases, thermal energy also increases.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

How does thermal energy affect the state of matter?

Back

Increased thermal energy can change a solid to a liquid (melting) or a liquid to a gas (evaporation).
