Density8.29 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
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?
