Pour granulated sugar into a beaker up to the 100 cm3 mark. Can we say that the volume of rhubarb sugar in this case is 100 cm3? Why? Will the amount of sugar be measured more or less accurately if powdered sugar is poured into a beaker?
No, the volume of sugar is less than 100 cm3, since the space between the sugar crystals in the beaker is filled with air and 100 cm3 is the sum of the volume of the crystals and the air between them.
If sugar is ground into powder, then the resulting smaller crystals will settle in a beaker denser, that is, there will be less air between them and the volume filled with powder will more closely correspond to the volume of sugar.
