Question

A solids floats submerged in a liquid. When the liquid is heated, which of the following is most likely to happen? (A) Solid may sink (B) Solid may float with a part outside the surface (C) Solid may first sink and then rise upwards (D) Solid may oscillate vertically

The density of the liquid will decrease on heating. However, the relative change in volume of the solid will be negligible as compared to that in density of liquid. Hence, upthrust acting on the solid will decrease and the solid will sink.
