A piece of ice is floating in a jar containing water. What will be the effect on the level of water in jar, when ice melts and the temperature of water falls from `4^(@)C to 1^(@)C` .

Explanation

The level of water in a jar rises, when the whole ice will melt and temperature changes from `4^(@)C` to `1^(@)C`. It is so because, the density of water is maximum at `4^(@)` and is less at `1^(@)C`. Due to it, the given mass of the water in jar will oc cupy more volume at `1^(@)C` than at `4^(@)`.
