3 physical properties the characteristics of a substance that can be observed or measured without changing the substance

4 solid the state of matter that has a definite shape and definite volume

5 liquid the state of matter that has a definite volume but no definite shape (liquids take the shape of their container)

6 gas the state of matter that has no definite shape or volume

8 weight the measure of the pull of gravity on an object (measured using a scale)

9 volume the amount of space an object takes up (measured using a graduated cylinder, beaker or flask)

11 evaporation the process by which a liquid changes to a gas

12 condensation the process by which a gas changes into a liquid

13 freezing point the temperature at which a substance changes from a liquid to a solid

14 melting point the temperature at which a substance changes from a solid to a liquid

15 boiling point the temperature at which a substance changes from a liquid to a gas

16 solubility the ability of one substance to be dissolved in another substance

17 reactivity the ability of a substance to go through a chemical change

18 combustibility the chemical property of being able to burn

19 mixture a combination of two or more different kinds of matter where each kind of matter keeps its own physical properties
