16 Density Mass of an object divided by its volume. Can be used to identify a substanceThe density of water is 1.0g/mL
17 Boiling PointThe temperature in which a liquid becomes a gas.
18 Melting PointThe temperature in which a solid becomes a liquid.
19 StateThere are three states of matter:SolidLiquidGas
20 LiquidMatter with a definite volume but no definite shape that can flow from one place to another.
21 GasMatter that does not have a definite shape or volume; has particles that move at high speeds in all directions.
22 SolidMatter with a definite shape and volume; has tightly packed particles that move mainly by vibrating.
