Ice floating on water in a beaker when ice completely melts then level of water in beaker

Expert Answer
Increase in water level is due to displaced volume of water. Displaced volume of water is due to partially immersed volume of ice.
When ice melts, volume of water equal to displaced volume is added to the container. Hence there will not be change in the water level.
Above statement is approximation. If you want to be very accurate, the answer is, water level decreases once the ice starts melting.
This decrease in water level may not be noticeable if volume of container is large. Density of ice is less than water, That is why, it floats in water.
For a given mass, when it is in the form of ice, its volume is more compare to when the given mass is in the form of water. Hence after melting of ice, volume of immersed part of ice decreases. Hence water level decreases. However this decreased amount in level is very less
