Question

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​

Answer 1

Answer:

hello samuel.

c) remains unchange

Answer 2

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
