When a liquid is heated in a glass vessel, its coefficient of apparent expansion is $1.03 \times 10^{-3}/^{\circ}C$. When the same liquid is heated in a copper vessel, its coefficient of apparent expansion is $1.006 \times 10^{-3}/^{\circ}C$.If the coefficient of linear expansion of copper is $17 \times 10^{-6}/^{\circ}C$, then the coefficient of linear expansion of the glass is
