Assuming temperature remaining constant calculate the pressure of the gas in the following:
The pressure of a gas having volume 1500 cm3 originally occupying 750 cc. at 5 ats. pressure.

उत्तर
V1 = 750 cc
P1 = 5 atm.
V2 = 1500 cc
P2 = ?
At constant temperature P1V1 = P2V2
∴ P2 = `("P"_1"V"_1)/"V"_2 = (5 xx 750)/(1500) = 5/2 = 2.5` atm.
