Density

Question	Answer
Density is...	MASS per unit VOLUME
Density is a measure of the compactness of a substance	It relates the mass of a substance to how much space it takes up
Density = Mass/Volume	Image: density_triangle (image/jpg)
The units for density are...	g/cm3 or kg/m3 1 g/cm3 = 1000 kg/m3
The density of an object depends on what?	It depends on what it's made of, density doesn't vary with size or shape.
When will an object float?	When it's density is less than that of the fluid. e.g. oil floats on water because it's density is 0.8 g/cm3 while the density of water is 1 g/cm3
How can you measure the volume of an irregular shaped object?	Put it in a measuring cylinder of water and take the old volume from the new volume
How can you find the density of a liquid?	Find the mass by weighing it in a measuring cylinder and taking away the mass of the cylinder. Find the volume with the measuring cylinder.
