Question
88 cm3 of nitrogen is at a pressure of 770 mm mercury. If the pressure is raised to 880 mmHg, find by how much the volume will diminish, the temperature remaining constant.
Solution
V = 88 cm3
P = 770 mm
P1 = 880 mm
V1= ?
T = T1
Using gas equation,
`"PV"/"T" = ("P"_1 "V"_1)/"T"_1`
`(770 xx 88)/"T" = (880 xx "V"_1)/"T"`
V1 = 77 cm3
Volume diminishes = 88 - 77 = 11 cm3
