Chemical Interactions Investigation 4

Front

What happens to particles when they lose kinetic energy?

Back

They move slower and contract.

Front

True or false: ALL particles move faster when heated, whether they are a solid, liquid, or gas.

Back

True

Front

Which state of matter can be compressed?

Back

A gas.

Front

Which has the LEAST kinetic energy: hot chocolate, a fire, or ice cream?

Back

Ice cream.

Front

What happens to the volume of a gas when it gets cold?

Back

It decreases and this is called contraction.

Front

Define kinetic energy in the context of particles.

Back

Kinetic energy is the energy that particles have due to their motion.

Front

What is the effect of heating a solid on its particle movement?

Back

The particles move faster and may eventually change to a liquid.

Front

What is contraction in terms of gas behavior?

Back

Contraction is the decrease in volume of a gas when it cools.

Front

What is the relationship between temperature and particle movement?

Back

As temperature increases, particle movement increases.

Front

Can liquids be compressed?

Back

No, liquids are not easily compressed compared to gases.
