What Is The Difference Between Physical And Chemical Change

However a physical change rearranges molecules and does not produce a new substance.

Chemical change a process in which chemical bonds are broken or created to make a new substance. Physical change refers to a change in which the molecules are rearranged but their internal composition remains same. Chemical change is a process in which the substance transforms into a new substance having different chemical composition. The difference between physical and chemical change is that a physical change merely changes the shape and size of the substance while a chemical change produces altogether new substance.

Physical change a process in which a substance changes its state of matter but chemical bonds stay intact. Often physical changes can be undone if energy is input. A substance can undergo physical and chemical changes. A physical change is a change in which the molecules of a substance are re arranged while their real composition remains unaltered.

A chemical change occurs on the molecular level and produces a new substance. The main difference between physical and chemical change is that a physical change does not change the chemical composition of a substance whereas a chemical change changes the chemical composition of substances. These changes can cause a substance to change its form or to change into a completely different substance. In physical substance the chemical composition remains the same whereas in chemical change the chemical composition is changed.
