Question

13. How does the density of water change when
Is heated from 4°C 10 10C ?​

Answer 1

Answer:

The density decreases from 0.9970 g/mL to 0.9718 as it is heated. This makes sense because, as heat is added to the liquid water, there is greater kinetic energy of the molecules and there are also more vibrations of the water molecules. ... Below 4 deg C, however, the density decreases again.

Answer 2

Explanation:

When water is heated from 0 0C, its volume decreases because its density increases and you can see this effect upto 4 0C. Because the density of ice is maximum at 4 0C. Afterwards as the density decreases the volume increases. The main reason for this is hydrogen bond in ice gets cleaved due to the melting of ice
