Density
density
density of a substance tells you how much mass is packed into a particular volume
density = mass over volume
units
units of density = units of mass over units of volume = grams over cm cubed = g cm -3
kilogram over metre cubed = kg m -3
triangle mass over density x volume
find mass - density x volume
find density = mass over volume
find volume = mass over density
Activities
To measure density of rectangular block
put block on scale and read mass, use ruler to measure height, width, and length to get volume, use mass over volume
to measure density of irregular solid
measure mass on scale, put object in overflow can full of water, let water overflow into graduated cylinder check volume, mass over volume
to measure density of a liquid
put liquid in graduated cylinder on a scale, use mass over volume
flotation
a solid will float in a liquid if the solid is less dense than the liquid
a liquid will float on top of another liquid if the liquid on top is less dense
boats float because filled with air making it less dense than water
