Question

If a liter of water is heated from 20 C to 50 C, what happens to its volume? a. The volume decreases. b. The volume increases. c. The volume first increases, then decreases. d. The volume first decreases, then increases.

Answer 1

Answer:

b.The volume increases.

Explanation:

We are given that a litre of water is heated from 20 degree celsius to 50 degree celsius .

Volume of water= 1litre

Volume of  liquid is directly proportional to temperature

When volume of liquid increases then temperature is also increases .

When temperature is increases then the volume is also increases .

When temperature decreases then the volume of liquid decreases.

When temperature is increases from 20 degree celsius to 50 degree celsius then the volume of water increases.

Hence , option b is true,

Answer :b.The volume increases.

Answer 2

If a liter of water is heated from 20 C to 50 C, the volume will increase.
