A Vessel having coefficient of cubical expansion ${\mathbf{\gamma }}_g$ contains liquid of coefficient of real expansion ${\mathbf{\gamma }}_R$ up to certain level. When vessel Is heated, match column I and column II

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