Which describes the particles in a liquid.
Slide past each other
Don't be stubborn. Use mass and volume to calculate this.

Speed up, slow down, break apart, or are unaffected? This happens to molecules when a substance loses heat energy?
Vibrate in place, slide past each other, fly around freely?
Which describes the particles in a gas.
Fly around freely
Because solid water is less dense than liquid water, you would expect it to do this.
Float
