### PROPERTIES OF MATTER, DENSITY and G.R.A.S.S. METHOD

 1 The three states of matter. _____ g / mL 2 All matter is made up of these. _____ density 3 Atoms in this state are vibrating in place and do not take the shape of their container because they have a strong attraction for each other and are held together in their lattice-work pattern. _____ statement = _____ 4 The ability to burn. _____ difficut to reverse 5 The ability to dissolve in another substance. _____ chemical change 6 A change in a substance that does not involve the formation of a new substance. _____ V = m / D 7 A change in which one or more new substances is formed. _____ a gas is produced 8 What proof of a chemical change is represented when the liquid changes from clear and colourless to pink? _____ atoms 9 What proof of a chemical change is represented when bubbles rise to the top as the chemicals are combined? _____ combustibility 10 What proof of a chemical change is represented when the chemicals are added together and the beaker becomes very warm? _____ pure 11 What proof of a chemical change is represented when a white gooey solid suddenly appears floating in the liquid? _____ heat is produced 12 What proof of a chemical change is represented when the cooked egg can never go back to the way it was when you first cracked the shell open? _____ solid 13 The usit for density of a liquid or an irregularly shaped object. _____ physical change 14 The unit for mass. _____ g 15 The unit for volume. _____ liquid 16 This is a substance that is only made up of one type of atom. _____ gas 17 A measure of how much mass is contained in a given volume of a substance. _____ given = _____ 18 The formula for findng density. _____ a change in colour 19 The formula for finding volume. _____ solid, liquid, and gas 20 The formula for finding mass. _____ analysis = _____ 21 The information in a problem that is in the question. _____ D = m / V 22 What you are being asked to find out in the problem. _____ a precipitate forms 23 This is the equation formula you will use to solve the problem (find the answer).. _____ solubility 24 Here you substitute your numbers into the equation and solve it, showing your work. _____ m = D (V) 25 Finally, you answer the question that problem asked you by writing it as a statement (sentence). _____ solution = _____ 26 Atoms in this state have broken their bonds but are still slightly attracted to each other, they take the shape of their container, and their speed of movement has increased but is not the fastest. _____ mL or cm3 27 In this state the atoms take the shape of their container, they do not have any attraction for each other, and are moving the fastest. _____ required = _____
