Density is defined as mass divided by volume. The mass of the object we know (5.6 g). In order to find the volume it occupies, we consider the water displaced in the graduated cylinder. The object raised the level of water by the same volume that it occupies. So the volume of the object is then:
A pure solid is heated and turns into a pure liquid.
Explanation:
No colour change recorded, only change of state, hence this is a physical change - physical changes I.e. change of state and temperature are not chemical reactions.
