प्रश्न
2 liters of gas is enclosed in a vessel at a pressure of 760 mmHg. If the temperature remains constant, calculate pressure when volume changes to 4 dm3.

उत्तर
V = 2 litres
P = 760 mm
V1 = 4000 m3 [1 dm3 = 4 litres]
P1= ?
`"PV"/"T" = ("P"_1 "V"_1)/"T"_1`
`(760 xx 2)/"T" = ("P"_1 xx 4)/"T"_1`
`"P"_1 = 760/2 = 380` mm
