Question

Law of conservation for mass holds true for physical changes.

• A. True
• B. False

Answer 1

The correct option is A

True

This statement is correct. Ice melting into water is a physical change. We take a piece of ice in a small flask and cork it, let the weight of this flask be W1. Heat the flask gently and ice slowly melts into water. Weigh the flask again, let this weight be W2. It is found that there is no change in the weight, W1 = W2.
