Question
Solids and liquids both expand on heating. The density of substance decreases on expanding according to the relation
when a solid is submerged in a liquid, liquid exerts an upward force on solid which is equal to the weight of liquid displaced by submerged part of solid. Solid will float or sink depends on relative densities of solid and liquid a cubical block of solid floats in a liquid with half of its volume submerged in liquid as shown in figure (at temperature T)
Imagine the depth of the block submerged in the liquid does not change on increasing temperature then
