Which one among the following statements with reference to the properties of water is not correct?
Options
- AThe specific heat of water is abnormally high.
- BLatent heat of fusion of water is very low.
- CDensity of water is higher than ice.
- 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 =80 ca / g . This is the amount that is required to convert 1 g solid ice into liquid water at its melting point.
