Phet States of Matter

The program should start with solid Neon. Describe the spacing and motion of the particles in a solid.

• Far apart and Rapid,Random Motion

• Packed Tightly and Vibrating in place

• Close Together and Slow motion

• Packed Tightly and Fast Motion

What happens as you cool the solid?

• The motion slows

• The motion speeds up

• The motion stays the same

• The motion jumps and freezes

Next, select the liquid phase. Describe the spacing and motion of the particles in a liquid.

• Packed tightly and fast motion

• Far apart and fast motion

• Close together and slow motion

• Close together and vibrating in place

What happens as you cool the liquid?

• The particles move faster

• The particles vibrate in place

• The particles freeze and jump out of place

• The particles slow down
