Ex: A block of ice floats on a liquid of density 1.2in a beaker then level of liquid when ice completely melt
A) Remains same
B) Rises
C) Lowers
D) (a), (b) or (c)
Correct Answer: B
Explanation & Trick:
The volume of liquid displaced by floating ice VD = M / σL Volume of water formed by melting
ice, VF = M / σW ; If σ1 > σW, then, M / σL < M / σW
i.e. VD < VF i.e. volume of liquid displaced by floating ice will be lesser than water formed and so the level if liquid will rise.
