1. The problem statement, all variables and given/known data
A cubical block of coeffficent of linear expansion [tex]\alpha[/tex] is submerged partially inside a liquid of coefficient of volume expansion [tex]\gamma[/tex]. On increasing the temperature of the system by [tex]\Delta[/tex]T, the height of the cube inside the liquid remains unchanged. Find the relation between [tex]\gamma[/tex] and [tex]\alpha[/tex] 3. The attempt at a solution Initially, V_{i} [tex]\rho[/tex]_{l} = V_{block}[tex]\rho[/tex]_{block} After heating, the height of the immersed part of the block remains unchanged. For this to happen, I don't understand whether the linear expansion or areal expansion of the block should be equal to the volume expansion of the liquid.
