A Chemical change may also cause a physical change; a physical change alone cannot lead to a chemical change. 3. A Physical change is superficial and can possibly be reversed; a chemical change is complete and permanent.
A physical change takes place without any changes in molecular composition. The same element or compound is present before and after the change. The same molecule is present through out the changes. Physical changes are related to physical properties since some measurements require that changes be made. Melting Point: As solid matter is heated it eventually melts or changes into a liquid state at the melting point. Ice (a solid form of water) melts at 0 oC and changes to the liquid state.
