Question
Assuming temperature remaining constant calculate the pressure of the gas in the following:
The pressure of a gas having volume 1000 cc. originally occupying 1500 cc. at 720 mm. pressure.
Solution
P1 = 720 mm
V1 = 1500 cc
P2 = ?
V2 = 1000 cc
At constant temperature P1V1 = P2V2
∴ P2 = `("P"_1"V"_1)/"V"_2 = (720 xx 1500)/1000 = 1080` mm
