Question
Assuming temperature remaining constant calculate the pressure of the gas in the following:
The pressure of a gas having volume 100 lits. originally occupying 75 dm3 at 700 mm. pressure.
Solution
P1 = 700 mm
V1 = 75 dm3
P2 = ?
V2 = 100 lits But 1 dm3 = 1 litre
∴ V2 = 100 dm3
At constant temperature P1V1 = P2V2
∴ P2 = `("P"_1"V"_1)/"V"_2 = (700 xx 75)/100 = 525` mm
