Question

Mass of water at ${10}^{\circ }C$ increases when heated to ${30}^{\circ }C$. True or false.

• A. True
• B. False

Answer 1

The correct option is B False

When a substance is heated its volume increases and its density decreases.

Considering anomalous expansion of water, after $4^{o}C$ its expansion is normal like the expansion of other liquids.

Because the mass is constant the volume of water increases.

Hence the sentence is false.
