Method

Density Measurement Method

To measure the density of a liquid, use a graduated cylinder to find the volume and a balance to find the mass. For a regular solid, calculate the volume using geometric formulas. For an irregular solid, submerge it in water and measure the volume of water displaced.

  1. a

    State the method used to measure the volume of an irregular solid.

    Aim for approximately 1 distinct marking point.
