Density : Density Density is a comparison of how much matter there is in a certain amount of space. Density : Density Density relates to the “compactness” or proximity of molecules in the substance Density : Density All substances have density including those if the various states of matter: liquids, solids, & gases Density is a relationship between mass and matter, represented in the chemical formula: Density Formula Triangle : Density Formula Triangle We can use the density “formula triangle” to calculate density, volume, or mass Practice Problems : Practice Problems Jack has a rock. The rock has a mass of 6g and a volume of 3cm3. What is the density of the rock? Practice Problems : Practice Problems Jill has a gel pen. The gel pen has a mass of 8g and a volume of 2cm3. What is the density of the rock? FINDING VOLUMES : FINDING VOLUMES Practice Problems : Practice Problems Jill has a crown made of gold which has a mass of 300 grams. She knows that gold has a density of 19.3 g/ml. What is the volume of her gold crown? Practice Problems : Practice Problems Mr. Bregar has a copper bracelet with a volume of 45 cm3. Knowing that copper has a density of 8.92 g/ cm3, what is the mass of the copper bracelet? Volumes of Regularly Shaped Objects : Volumes of Regularly Shaped Objects We use measurement and mathematical formulas to calculate the volume for such objects Volumes of Regularly Shaped Objects : Volumes of Regularly Shaped Objects Problem? : Problem? How do we find the volume of irregular shaped objects? Volume of Irregular Shaped Objects : Volume of Irregular Shaped Objects We can find the volume of an object indirectly by measuring its displacement. This was discovered by Archimedes and is called Archimedes' Principle Archimedes : Archimedes Displacement : Displacement When an object immersed in a fluid pushes the fluid “out of the way” The volume of the “stone” displaced the water. This “displacement” is the actual volume of the stone. Slide 19: 19 What is the density (g/cm3) of 48 g of a metal if the metal raises the level of water in a graduated cylinder from 25 mL to 33 mL? 1) 0.2 g/ cm3 2) 6 g/m3 3) 252 g/cm3 25 mL 33 mL Application of Density : Application of Density Application of Density : Application of Density How do we know if something will float? Buoyancy : Buoyancy An upward force, that tends to make an object float rather than sink. Buoyancy depends on density If the buoyancy force is greater than gravity, than an object floats Buoyancy Demonstration : Buoyancy Demonstration Changing the density of a liquid to control buoyancy Buoyancy Demonstration : Buoyancy Demonstration Liquid Layers Prediction : Liquid Layers Prediction Which liquid has the highest density? Which liquid has the lowest density? Which liquid has the middle density? Lets Try It Out : Lets Try It Out Liquid Layers : Liquid Layers Which layer has the highest density? Which layer has the lowest density? Liquid Layers : Liquid Layers Match the densities below to the liquid players: 10g/cm3 3g/cm3 6g/cm3 5g/cm3 Liquid Layers : Liquid Layers Imagine that the liquids on the right have the following densities: 15g/cm3 10g/cm3 3g/cm3 9g/cm3 7g/cm3 12g/cm3 Match the colors to the correct densities. 3g/cm3 7g/cm3 9g/cm3 10g/cm3 12g/cm3 15g/cm3 Slide 31: 31 Which diagram represents the liquid layers in the cylinder if (K) Karo Honey syrup (1.4 g/mL), (V) vegetable oil (0.91 g/mL,) and (W) water (1.0 g/mL) are mixed?
