Q72: A piece of ice is floating in water at 4º C in a beaker. When the ice melts completely, the water level in the beaker will (a) rise (b) fall (c) remains unchanged (d) unpredictable About the author Jade
Answer: Correct option is B Falls The density of water is maximum at 4 ∘ C. Let ‘x’ amount of ice has been melted. Then the volume of water at 20 ∘ C displaced to float that ‘x’ amount of ice will be higher than the volume of water that has been gained after melting of ice as both volumes have same masses ‘x’ but the density is higher at 4 ∘ C. consequently, the water level falls Option −B is correct Explanation: hope it will help ….
