Question

(c) State four main physical properties of water.
(iv)
(i)
(ii)
(iii)
(d) Explain anomalous expansion of water is an unusual physical property of
water.​

Answer 1

Explanation:

(c) Given the low molar mass of its constituent molecules, water has unusually large values of viscosity, surface tension, heat of vaporization, and entropy of vaporization, all of which can be ascribed to the extensive hydrogen bonding interactions present in liquid water.

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