Physical properties are affected by the physical change. For Example, when ice changes to water, there is a change in the physical state of ice, i.e. it changes from solid to liquid. If we cool the water again, ice will be formed making it a reversible reaction. Also, no new substance is formed in the above physical change. What is a Chemical ...
