Which one among the following statements with reference to the properties of water is not correct?

Options

  1. AThe specific heat of water is abnormally high.
  2. BLatent heat of fusion of water is very low.
  3. CDensity of water is higher than ice.
  4. DPure water is a non-conductor of electricity.

Correct answer

B. Latent heat of fusion of water is very low.

Step-by-step solution

Latent heat of fusion of water is very low: This is incorrect. Water actually has a high latent heat of fusion, which is the amount of heat required to convert ice at its melting point into water without changing its temperature. The latent heat of fusion =80ca/g=80 \mathrm{ca} / \mathrm{g}. This is the amount that is required to convert 1 g solid ice into liquid water at its melting point.
