Question

How does the density of water changes
when :
a it is heated from 0c to 4c
b) It is heated from 4c to 10°C.
​

Answer 1

Answer:

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.

Answer 2

a) When water is heated from 0 degree c, it will contract on heating and expand on cooling
b) Water will expand on cooling and contract on cooling.
