Question

The behavior of water around 4˙C

Temperature is called as ______

expansion.

A. Linear

B. Cubical

C. Thermal

D. Anomalous​

Answer 1

Ans. D

Sol. The anomalous expansion of water is

an abnormal property of water where it

expands instead of contracting when the

temperature goes from 4C to 0C, and it

becomes less dense.

● Hydrogen bond is responsible for the

anomalous expansion of water below 4C.

● Water is denser than ice while almost

all the other substances are denser in

solid form than in liquid form.
