1.	A gas bulb containing air is connected to an open limb manometer at 27^(@) C and at 750 mm Hg . Assuming that intially the level of Hg in the both limbs were same . The bulb was heated to 77^(@)C , what will be differences in the levels of Hg in two limbs ? (Assuming the volume difference of the gas produced is negligible at higher temperature) .
Answer» <P>7.5 cm Hg 8 cm Hg 6 cm Hg 12.5 cm Hg Solution :`because (P_(1))/(T_(1)) = (P_(2))/(T_(2)) , (750)/(300) = (P_(2))/(350)` `therefore P_2 = 875` mm Hg `therefore` So , difference in height= `875 - 750 = 125` mm Hg = 12.5 cm of Hg
