Question

a sample of N2 gas is kept in 5l cylinder fitted with a piston at 3.5 atm and 25degree celcius . if its pressure is changed to 2 atm at the same temperature what would be the new volume

Answer 1

Answer:

New volume = 8.75 L

Explanation:

According to Boyle's law,

P1V1 = P2V2

Here, P1 = 3.5 atm; V1 = 5 L; P2 = 2 atm;

V2 =?

V2 = (P1V1)/(P2)

V2 = (3.5x5)/(2)

V2 = 8.75 L
