An empty LGP cylinder weighs 14.8kg. When full, it weights 29.0kg and shows a pressure of 3.47 atm. In the course of use at ambient temperature, the mass of the cylinder is reduced to 23.0kg. The final pressure inside of the cylinder is______atm. (Nearest integer)

0 Follower 3 Views

Contributor-Level 10

Mass of empty cylinder = 14.8 kg

Mass of cylinder when full = 29 kg

Mass of gas in cylinder when filled; W₁ = 29 – 14.8 = 14.2 kg

Mass of gas in cylinder after using, W₂ = 23 – 14.8 = 8.2 kg

Initial pressure ; P₁ = 3.47 atm

Final pressure ; P₂ =?

Using

$P V = \frac{W}{M} R T$

$P_{1} V = \frac{W_{1}}{M} R T . . . . . . . . . . (I)$

$P_{2} V = \frac{W_{2}}{M} R T . . . . . . . . . . . (I I)$

$\frac{P_{1}}{P_{2}} = \frac{W_{1}}{W_{2}}$

$\frac{3.47}{P_{2}} = \frac{14.2}{8.2}$

P₂ = atm
