The way molecules in a substance move around relative to each other ia often related to the Freedom of movement
- Gas vibrate and move freely at high speeds.
- Liquid vibrate, move about, and slide past each other.
- Solid vibrate (jiggle) but do not move from place to place.
In liquids, molecules can move around and slide past each other and a liquid oftdn take on the shape of the container it is being held in.
A molecules freedom of movement in a gas is when the molecules in a gas have more freedom of movement than molecules in a liquid.
Conclusively, A decrease in the speed of the molecules gives room for the attractions between molecules to bring them a little closer together.
