In a science exhibition, a student called Rishi performed the following experiment. She took two containers of the same dimensions and filled one of them with wax and the other one with ice. She placed both of them in a boiling water bath. What difference could she observe during the melting of these two substances? Also predict the reason for the observed difference.

1.	In a science exhibition, a student called Rishi performed the following experiment. She took two containers of the same dimensions and filled one of them with wax and the other one with ice. She placed both of them in a boiling water bath. What difference could she observe during the melting of these two substances? Also predict the reason for the observed difference.
Answer» Solution :Since the density of solid wax is GREATER than the molten wax, molten wax will OVERFLOW. Density of ice is less than that of water. As a result, water FORMED from ice occupy LESSER VOLUME instead of overflowing.
