Particle expansion and contraction

Front

What is the instrument used for measuring temperature?

Back

Thermometer

Front

What is expansion?

Back

An increase in volume of a substance when temperature increases.

Front

What happens to a cold metal spoon placed in boiling water?

Back

Energy is transferred from the water to the spoon.

Front

If particles have high kinetic energy, what can we say about their temperature?

Back

They usually have a high temperature.

Front

What happens to gas particles when you push the plunger of a syringe down?

Back

There are the same amount of air particles in each syringe.

Front

What is contraction?

Back

A decrease in volume of a substance when temperature decreases.

Front

What is kinetic energy?

Back

The energy that a particle possesses due to its motion.

Front

How does temperature affect particle movement?

Back

Higher temperature increases particle movement, while lower temperature decreases it.

Front

What is thermal energy?

Back

The total energy of all the particles in a substance.

Front

What occurs during thermal expansion?

Back

Particles move faster and spread apart, causing an increase in volume.
