The closed cylinder shown in figure has a freely moving piston separating chambers 1 and 2. Chamber 1 contains 280 mg of N 2 gas, and chamber 2 contains 200 mg of helium gas. When equilibrium is established, what will be the ratio L 2 /L 1 ? (Molecular weights of N 2 and He are 28 and 4).
Text Solution
Verified by ExpertsThe correct answer is:
5
(5)
At equilibrium pressure in each chamber is the same
n 1 = 
= 10 -2 ; n 2 = 
= 5 × 10 -2
Let A = area of cross section of cylinder.
P = 
= 
⇒ 
= 
= 5 Ans.
