lf the temperature of a small quantity of water in a closed container is gradually increased from 0o to 40oC then the density of the water within this range
A
increases for a while and then decreases
B
decreases for a while and then increases
C
increases gradually
D
decreases gradually
E
remains the same
Verified Correct Answer: A.
Physical Principles & Numerical Solution
Water has a peculiar property. When temperature rises between 0 to 4^\circC water is not going to expand but it is going to contract. This special property is called anomalous. Therefore at 4^\circC volume of the water is minimum and the corresponding density is maximum.
