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.

उत्तर
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

A certain mass of gas occupied 850 ml at a pressure of 760 mm of Hg. On increasing the pressure it was found that the volume of the gas was 75% of its initial value. Assuming constant temperature, find the final pressure of the gas?
It is required to reduce the volume of a gas by 20% by compressing it at a constant pressure. To do so, the gas has to be cooled. If the gas attains a final temperature of 157°C, find the initial temperature of the gas.
The pressure on one mole of gas at s.t.p. is doubled and the temperature is raised to 546 K. What is the final volume of the gas ? [one mole of a gas occupies a volume of 22.4 litres at stp.]
According to Charles’s law, at constant pressure, the temperature is inversely proportional to volume.
