Properties Of Solids And Liquids Question 202

Question: A block of ice floats on a liquid of density 1.2in a beaker then level of liquid when ice completely melt[IIT-JEE 1994]

Options:

A) Remains same

B) Rises

C) Lowers

D) (a), (b) or (c)

Show Answer

Answer:

Correct Answer: B

Solution:

The volume of liquid displaced by floating ice VD=MσL

Volume of water formed by melting ice, VF=MσW If σ1>σW,

then, MσL<MσW 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.
