To describe whether paper torned into several pieces is a physical change or not. Concept Introduction: In the physical property, the material or substance will not change its chemical identity only changes its physical state like solid into liquid or liquid into gas. For example changing in physical state like ice melts into water. In the chemical property, the material or substance will change its chemical identity means there is a new substance formed by the formation heat, energy or gas. Like sodium readily reacts with water and farms another compound. In the chemical change substance lose the identity while in the physical change substance does not lose the identity.
