Test Lab #4 Kinetic Energy2024

Front

What happens to particles when heat energy is removed from a substance?

Back

The particles lose kinetic energy.

Front

What occurs when the speed of air particles decreases?

Back

The temperature decreases.

Front

What happens to the particles of a solid when heat energy is added?

Back

The particles vibrate faster.

Front

What decreases when a substance is cooled?

Back

Temperature, particle kinetic energy, and space between the particles.

Front

Do heat particles exist?

Back

No, heat particles do not exist.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

How does temperature relate to particle movement?

Back

Higher temperature means particles move faster, while lower temperature means they move slower.

Front

What is the effect of adding heat to a liquid?

Back

The particles in the liquid gain energy and move faster, potentially leading to a change in state.

Front

What is the relationship between kinetic energy and temperature?

Back

Kinetic energy is directly related to temperature; as temperature increases, kinetic energy increases.

Front

What happens to the space between particles when a substance is heated?

Back

The space between particles generally increases as they gain energy and move apart.
