When a liquid is heated in a glass vessel, its coefficient of apparent expension is `1.03xx10^(-3)//^(@)C.` When the same liquid is heated in a copper vessel, its coefficient of apparent expansion is `1.006xx10^(-3)//^(@)C.` If the coefficient of linear expension of copper is `17xx10^(-6)//^(@)C,` then the coefficient of linear expansion of glass

Options

A. `8.5xx10^(-4)//^(@)C`
B. `9xx10^(-6)//^(@)C`
C. `27xx10^(-6)//^(@)C`
D. `10xx10^(-4)//^(@)C`

Answer

B

Explanation

Here, `gamma_(r)=gamma_(ag)+3alpha_(g)=alpha_(ac)+3alpha_(c)`
`rArr1.03xx10^(-3)+3alpha_(g)=1.006xx10^(-3)+3xx(17xx10^(-6))`
`alpha_(g)=9xx10^(-6)//""^(@)C`
