Distinguish, differentiate, compare and explain what is the main differences between chemical and physical Change.
Differences between Chemical and Physical Change
1. A change in which one or more new substances are formed is called a chemical change. Physical changes are changes in the physical properties of substances.
2. The example of chemical changes: Milk goes sour, A match is lift, digesting food etc. The example of physical change is: Aluminum foil is cut in half, A juice box in the freezer freezes etc.
3. New substances are produced in a chemical change. No new substances are formed in physical changes.
4. Chemical changes are irreversible. For example, Rusting is nothing but the reaction of iron substances with moist air forming (new sunspace) Fe2O3 (Ferric (III) oxide) is an irreversible change. Physical changes may be reversible. For example, Ice melts to the liquid. Here no new substances are formed. The solid ice which has melted to liquid both have the same composition H2O (water). The only change in the physical shape which is reversible by freezing the melted water once again.
