8. 2,1 How much matter an object contains… MASS

9. 2,2 A group of two or more atoms joined together by chemical bonds… Ex. H 2 O, table salt, sugar COMPOUND

10. 2,3 Fog, butter, toothpaste, and paint are examples of this kind of mixture… COLLOID

11. 2,4 Alters the form of substance but does not change it to a different substance… Ex. Evaporating, dissolving, and breaking PHYSCIAL CHANGE

12. 3,1 The amount of mass per unit of volume… DENSITY

13. 3,2 Simplest substances that cannot be broken down by chemical or physical means… Ex. Hydrogen (H), Oxygen (O), and Iron (Fe) ELEMENT

24. Final Jeopardy Question: An unknown substa nce has a de nsity of 7.87 g/cm 3 a nd mass of 15.74 grams what i s its volume? Will i t sink or float in water? Show ALL WORK on white board

25. VOLUME = MASS / DENSITY VOLUME = 15.74 g / 7.87 g/cm 3 VOLUME = 2 cm 3 SUBSTANCE WILL SINK IN WATER Final Jeopardy Answer:

26. Final Jeopardy Question: An unknown substance has a density of 0.85 g/cm 3 and volume of 3.38 cm 3 what is its mass? Will it sink or float in water? Show ALL WORK on white board

27. MASS = DENSITY x VOLUME MASS= 0.85 g/cm 3 x 3.38 cm 3 MASS = 2.873 g SUBSTANCE WILL FLOAT IN WATER Final Jeopardy Answer:
