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 glass is

Here,        γ$$r=$$γ$$ag+3$$α$$g=$$γ$$ac+3$$αc⇒       $$1.03$$×$$10-3+3$$α$$g=1.006$$×$$10-3+3$$×$$17$$×$$10-6$$⇒                                   α$$g=9$$×$$10-6/C$$  ∘

	Column - I		Column - II
a	$γ_{g} < γ_{R}$	p	liquid level rises continuously from beginning
b	$γ_{g} = γ_{R}$	q	liquid level falls continuously from beginning
c	$γ_{g} > γ_{R}$	r	liquid level remains same
d	$γ_{g} = 0$	s	liquid level first falls and then rises
