State of matter recap

Which state of matter do particles move the fastest

• Gas

• Liquid

• Solid

Is there a state of matter where the particles are not moving? Why or why not?

Select the States part of the simulation

Describe the relative motion (speed) of the particles in each phase.

Solid:

Liquid:

Gas:

Prediction: (before you do the simulation)

How does adding energy to a solid affect the motion of the particles?

How can a gas at room temperature (like oxygen) become solid?

Experiment (on the states tab)

Start with solid Argon and explain​ how to make Argon change to the liquid state and then to the gaseous state.

Experiment (on the states tab)

. Start with gaseous Argon and explain​ how to make the Argon change to the liquid state and then to the solid state.

Experiment (on the states tab)

Explain how the absorption of energy (heating) affects the speed of the particles in a substance.

Experiment (on states tab)

Explain how the release of energy (cooling) affects the speed of the particles in a substance.

Experiment (on the states tab)

Can you make the particles of any of the substances stop moving?

When you apply heat energy to a substance, where does the energy go? Think about the law of conservation of energy.
