Hint: Chemical change is an irreversible process in which both chemical and physical property of a substance changes. Physical change is a reversible process in which only physical property of a substance changes.
Complete answer:
Physical Change:
- Physical changes are changes affecting the form or state of a chemical substance, but not its chemical composition.
-Physical changes are used to separate mixtures into their component compounds and cannot be used to separate compounds into chemical elements or simpler compounds.
Water exists in solid form as ice, as water in liquid state, and as steam in gaseous state. All are the three physical states of water, but all the three forms contain .
-Other examples are whipping egg albumin, crushing of tomato and breaking of a bar magnet.
Chemical Change:
-When there is change in chemical properties, such change is called chemical change, also known as chemical reaction.
-When chemical change occurs, there is breaking of bonds between the molecules and there is change in composition of substance.
-There is simultaneous making and breaking of bonds in chemical change.
-Combustion, rusting and fermentation are examples of chemical change.
In ripening of fruits, the chemical composition of fruit changes and it is irreversible. Hence ripening of fruits is a chemical change.
Growing a tree from a plant is an irreversible change which is accompanied by change in chemical composition. Hence, it is a chemical change.
From the above points, we can conclude that ripening of fruits and growing of plants into a tree is an example of chemical change.
So, the correct option is (B) Chemical change.
Note:
After chemical change, a new product is formed which has different chemical composition than original substance. The physical change is not associated with change in chemical composition and chemical composition of substance is the same before and after physical change.
