The cubic expansivity of mercury is 1.8 x 10-4K-1 and the linear expansivity of glass 8.0 x 10-6K-1, calculate the apparent expansivity of mercury in a glass container

real expansivity = cubic expansivity + apparent cubic expansivity

but instead of cubic expansivity, linear expansivity was given so we have to convert
cubic expansivity= 3* (8.0x10^-6) = 2.4x10^-5

subtract your cubic expansivity from the real expansivity given
apparent expansivity = (1.8x10^-4) - (2.4x10-5) = 1.56x10^-4 (B)

Real cubic expansivity=apparent cubic expansivity+cubic expansivity of container
1.8×10^-4= x +8×10^-6
X=1.8×10^-4 -8×10^-6
X=1.72 ×10^-4

real expansivity =apparent expansivity +cubic expansivity

but apparent expansivity =3×linear expansivity
=3×8.0×10^-6=0.24×10^-4

real expansivity =0.24×10^-4+1.8×10^-4=2.04×10^-4K^-1
