Answer: occurs when some of the properties of a material change, but the substance
in the material remain the same
physical change
Examples of physical changes include: Crumpling a sheet or paper (a good example of a reversible physical change) Breaking a pane of glass (the chemical composition of the glass remains the same) Freezing water into ice (the chemical formula is not changed) Chopping vegetables (cutting separates …
Physical change is a type of change where the physical properties of matter change. A change of state of matter change in colour odour solubility etc. all are examples of physical change. During a physical change neither the composition nor the chemical nature of matter is changed. During this change molecules rearrange themselves without affecting the internal composition. A physical change doesn’t affect the chemical property.
Physical changes involve states of matter and energy. No new substance is created during a physical change although the matter takes a different form. The size shape and color of matter may change. Physical changes occur when substances are mixed but don’t chemically react.

Physical change is an important concept in chemistry; it describes changes to things that don’t result in brand-new substances. Physical change upholds the molecular structure of a substance. Water for example is composed of two hydrogen molecules and one oxygen molecule no matter whether it’s boiling or frozen.
A physical change involves a change in physical properties. Examples of physical properties include melting transition to a gas change of strength change of durability changes to crystal form textural change shape size color volume and density. An example of a physical change is the process of tempering steel to form a knife blade. …
