mg=Ï1V1g=Ï1lA1g
Ï1lA1g=Ï2lA2g (A is the bottom area of the cube)
Ï1A1=Ï2A2
Ï1/Ï2=A2/A1=l22/l12
1+γΔT=1+2αΔT
plzz somebody explain the last part of this
A cubical block is floating inside a bath. The temperature of system is increased by small temperature ΔT. It was found that the depth of submerged portion of cube does not change. Find the relation between coefficient of linear expansion (α) of the cube and volume expansion of liquid (γ).
