Question

1. If a gas at 37 degrees Celcius occupies 2.9 L at a pressure of 380 torr, what will be the new

volume at a pressure of 1.5 atm?
LAW:

Answer 1

0.96 litre will be the new volume of the gas at a pressure of 1.5 atm.

Step-by-step explanation:

Data given:

initial temperature of the gas = 37 degrees

initial pressure P1 = 380 torr or 0.5 atm

initial volume of gas V1= 2.9 litre

final volume V2 = ?

final pressure P2 = 1.5 atm

Assuming that temperature remains constant, the formula used is of Boyle's Law:

P1V1 = P2V2

Rearranging the equation to know the value of final volume of the gas:

V2 =
`(P1V1)/(P2)`

V2 =
`(0.5 X 2.9)/(1.5)`

V2 = 0.96 LITRE

the volume of the gas decreases as the pressure of the gas increases.
