| 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. |
