Density Video from Zoom Science I. Measuring Density A. density: mass per unit volume -in other words, how much stuff there is per unit of space B. Properties of Objects with Different Densities 1. liquids/objects with lighter densities will float on liquids/objects of heavier densities C. Formula for Density 1. D = m x V D = density m = mass V = volume 2. Units of Density -regular object = g/cm3 -irregular object = g/mL 3. Examples Ex1 Volume of water = 5 mL, mass of water = 20 g. Density? 4 g/mL Ex2 Volume of white board eraser = 10 cm3 Mass of eraser = 5 g. Density? 0.5 g/cm3 Attachments Density of a Regular Object - independent practice finding the density of regular shaped objects Density of an Irregular Object - independent practice finding the density of irregular shaped objects |
