Review - Density by Water Displacement

Master density calculations with water displacement! Learn material properties.

Objective:Find the density of an unknown irregular objectQuestion 1 (Part 1)"Find the mass"What is the MASS of the object?Hint: Add all the Moveable Masses 335 grams (g) 300 grams (g) 30 grams(g) Ask questions! Question 2 (Part II)(Find the Volume by water displacement method)Find the Volume of the rock by subtraction the two water levelsVolume = Water level(after) "minus" Water level(before)= 30 mL - 20 mL 30 mL 20 mL 10 mL read the whole problem! Question 3(Part III)Find the Density Density = MASS question 1 (Mass=335 g)From question 2 (Volume od the Rock= 10 mL)Find theDENSITYof the rock 335 g 33.5 g 0.335 g Divide mass by volume(Youmay use a calculator) Question 4Find theDENSITYby dividingMASSbyVOLUME, the use the table to identify the materialMass= 200 gramsVolume= 74.1 mLDensity=? DENSITY = Mass / Volume (divide)Material=? Lead Aluminum Gold Find the density then look at the table to find the material Question 5 Write (type)all the properties ofMETALS Question 6 Write (type) all the properties of METALLOIDS (Semi-Metals) Question 7 Write (Type) all the properties of NONMETALS Question 8The higher the number the harder the material to scratchCan Gypsum scratch a Topaz? No, Topaz is harder substance than Gypsum Yes, Gypsum is harder than Topaz Batman can do anything Study the table Question 9What type of material would you use if you want to make a cooking pan? Nonmetal Metal Metalloid Study the table Question 10What material would you use if you want to insulate your house for the winter? Metal Metalloid Nonmetal Ice
