Question

2. Observe the following graph.
Considering the change in volume of
water as its t
temperature is raised
from 0 °C, discuss the difference in
the behaviour of water and other
substances. What is this behaviour
of water called?
​

Answer 1

Answer:anomalous expansion of water

Explanation:

The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4o C to 0o C, and it becomes less dense. ... The density becomes less and less as it freezes because molecules of water normally form open crystal structures when in solid form.

Answer 2

Answer:

Water, instead of expanding, contracts between 0oC to 4oC. After 4oC, it shows the normal behavior of expansion as is shown by other substances. Thus, at 4oC, water posses maximum density and minimum volume. This behavior of water between 0oC to 4oC is known as anomalous behavior of water.
