Question

Assertion (A): Density of ice is less than water. Reason (R) : Density of ice is maximum at 4 degrees * C . Now choose the correct option. (1) Both (A) and (R) are true and correct explanation of (A) . (R) is the (2) Both (A) and (R) are true but (R) is not the correct explanation of (A). (3) (A) is true but (R) is false. (4) (A) is false but (R) is true.​

Answer 1

Answer:

The density of ice is 0.9167 g/cm3 at 0 °C, whereas water has a density of 0.9998 g/cm³ at the same temperature. Liquid water is densest, essentially 1.00 g/cm³, at 4 °C and becomes less dense as the water molecules begin to form the hexagonal crystals of ice as the freezing point is reached.
