Density 8.29 Density is how much mass (heaviness) is packed into an object’s volume (space) Density is basically “bigger D = sinks or smaller D = floats”. 2) The base unit is the gram/cm3. Water has a density of 1 g/cm3. If something has a bigger density than water it sinks. If it has a smaller density than water it floats. 3) If you add more heaviness= bigger D = sinks Take away heaviness= smaller D = floats Add space= smaller D= floats Take away space= bigger D= sinks If you change the shape (heaviness/space in the same ratio) the DENSITY DOESN’T CHANGE 1) W. is density? 2) W. is the metric unit for density? 3)W. are some trends with calculating density?

DENSITY Mass per unit volume Base unit is the gram/cm3 or (gram/ml) Formula: D= M/V M = D * V V = M/D GIVE EXAMPLES SHOW HOW TO MEASURE

EXIT SLIP What is the density of an object with a mass of 60g and a volume of 2cm3? You are given the following information: mass= 48g; volume=24 cm3. What is the density of this substance? If you have a gold brick that is 2cm by 3cm by 4cm and has a density of 3 g/cm3, what is its mass?
