The answer is given as follows:
All substances has various physical and chemical properties. Physical properties are those characteristics that can measure without changing the composition of the substances under study, such as mass, color, and volume. Chemical properties explain the characteristic ability of a matter to react to form new substances; eg susceptibility to corrosion , its flammability .
Chemical changes occures when bond broken or form in a matter or subatance.
When ice heated its started to melt becuase bonds between the hydrogen molecules (weak hydrogen bonding) started to break and its convert into water. But when a liquid cooled its solidified and become solid after cooling becuase hydorgen bonding between the molecules.
