Assuming temperature remaining constant calculate the pressure of the gas in the following:
The pressure of a gas having volume 380 lits. originally occupying 800 cm3 at 76 cm. pressure.

उत्तर
V1 = 800 cm3
P1 = 76 cm
V2 = 380 lit. = 380 × 1000 cm3
P2 = ?
At constant temperature P1V1 = P2V2
∴ P2 = `("P"_1"V"_1)/"V"_2 = (76 xx 800)/(380 xx 1000) = 0.16` cm of Hg
