Question

Which one of the following factor is involved in a change?

(a) Heating
(b) Force
(c) Chemical reaction
(d) All of these​

Answer 1

Answer:

all of these is correct answer

Answer 2

All of these are involved in a change.

• By the application of heat we can change the physical states (solid, liquid, gaseous) of a substance, which is basically a physical change. So, heating is certainly involved in a change. (Application of heat can also cause chemical change by thermal decomposition reaction.)
• By the application of force we can change the shape of a substance, which is another physical change. So, force is certainly involved in a change.
• In a chemical reaction, new products are formed from the initial reactants. It is considered as the chemical change. So, chemical reaction is also involved in a change.
• So, the final conclusion is, every mentioned factor is related to change.
