Question

a gas contained in a vessel of capacity x litres at 20 atm. when this container is connected to another empty container of same capacity. find the new pressure of gas assuming the pressure to be constant

Answer 1

When two containers are connected to each other, Diffusion takes place and gas will move to another container till concentration in both container becomes equal.

So P equals n over v R T

     Temperature is constant and concentration is constant

 

so Pressure will be same  

P1=P2

P2=20 atm

Answer 2

When two containers are connected to each other, Diffusion takes place and gas will move to another container till concentration in both container becomes equal.

So P equals n over v R T

     Temperature is constant and concentration is constant

 

so Pressure will be same  

P1=P2

P2=20 atm
