When a liquid in a glass vessel is heated, its apparent expansion coefficient is 10.30 x 10 -4 °C . When the same liquid is heated in a metal vessel, its apparent expansion coefficient is 10.06 x 10 -4 °C . If the coefficient of linear expansion of glass = 9 x 10 -6 °C, what is the coefficient of linear expansion of metal?

17 x 10 -6 °C -1
Here, 
ag =10 .30 x 10 -4 °C -1
am = 10.06x 10 -4 0 C -1
g = 9 x 10 -6 0 C -1 
m = ?
Now, 
r = 
ag + 
g = 
am + 
m
10.30 x10 -4 + 3 x 9 x 10 -6 = 10 .06 x10 -4 + 
m 
= (10 .30 +0.27-10.06)10 -4 - 0 .51 x10 -4
