MCQ
The matter is neither created nor destroyed during any physical or chemical change. This statement is of the :
  • A
    Law of constant proportion.
  • ✓
    Law of conservation of mass.
  • C
    Law of reciprocal proportion.
  • D
    Law of multiple proportion.
✓

Answer

Correct option: B.
Law of conservation of mass.
The law of conservation of mass states that "the matter is neither created nor destroyed during any physical or chemical change".
The Law of conservation of Mass states that matter can be changed from one form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant. The total mass of the universe is constant within measurable limits.
