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 fraction submerged does not change on increasing temperature the relation between $gamma subscript L end subscript$ _L and $alpha subscript S end subscript$ is

$γ_{L} = 3 α_{S}$
$γ_{L} = 2 α_{S}$
$γ_{L} = 4 α_{S}$
$γ_{L} = (3 / 2) α_{S}$

The correct answer is: $gamma subscript L end subscript equals 3 alpha subscript S end subscript$
