A vessel having coefficient of cubical expansion ${\mathbf{\gamma }}_{\mathrm{g}}$ contains liquid Of coefficient of real expansion r_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	${\mathrm{\gamma }}_{\mathrm{g}}={\mathrm{\gamma }}_{\mathrm{R}}$	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

3	q	r	s	p
4	r	q	p	s
