Question
Some pieces of impurity (density = ρ) is embedded in ice. This ice is floating in water (density = ρw). When ice melts, level of water will
Options
A.fall if ρ > ρw
B.remain unchanged, if ρ < ρw
C.fall if ρ < ρw
D.rise if ρ > ρw
Solution
Level will fall if initially the impurity pieces were floating along will ice and later it sinks.
Level will remain unchanged if initially they were floating and later also they keep floating.
Level will remain unchanged if initially they were floating and later also they keep floating.
