11Density of liquid is M / V1
F = V2dg
mg =V2dg
m = A*hd
Since the height remains the same h is constant
New A2 = A(1+2 α*T)
Since 2α = β where α is coeff of linear expansion while β is coeff of area expansion
Change in density = M/V1(1+γT)
m = h *A * M/V1
After increase of T
m = h * A(1+ 2α*T) * M/V1(1+γT)
m = m
2α = γ
