Density + matter

• A solid's particle arrangement is that they are all touching is a compacted shape and a fixed volume.
• A liquid's particle arrangement is that they're close together but can move, no fixed shape so it can flow and fit to container.
• A gas' particle arrangement is none of them touching, all move freely and rapidly, no fixed shape.
• grams divided by 1000 = kg
• kg x 1000 = grams
• Density = mass divided by volume
