Question
Chapter 10, Problem 133QP
Interpretation Introduction
Interpretation:
A diagram is to be drawn to show the process of the melting of chlorine.
Introduction:
Melting is the process of conversion of a solid into a liquid due to the application of heat. There is an increase in the internal energy of the solid. It is an endothermic process as the solid absorbs energy from the environment to break the binding forces, which enables the molecules to move freely and form a liquid.
