Question

how does the density of water changes when :
(a) it is heated from 0 Celsius to 4 Celsius
(b) it is heated from 4 Celsius to 10 Celsius?

Answer 1

Answer:

(a) it is heated from 0 Celsius to 4 Celsius

Answer 2

• when water is heated from O O,C it's volume decreases because it's density increases and you can see this effect upto 4 OC. because the density of ice is maximum at 4 OC. After wards as the density decreases. The main reason for this is hydrogen bond in ice gets cleaved due to the melting of ice.

• It is heated from 4°C to 10°C ? Solution:.. (b) The density of water is maximum at 4°C . it decreases when it is colled from 4°C to 0°C or it's heated above 4°C.
