Two flasks X and Y have capacity 1 and 2 l, respectively, and each of them contains 1 mole of a gas. The temperature of the flask is so adjusted that average speed of molecules in X is twice as those

Question

Two flasks X and Y have capacity 1 and 2 l, respectively, and each of them contains 1 mole of a gas. The temperature of the flask is so adjusted that average speed of molecules in X is twice as those in Y. The pressure in flask X would be

TestHub · Accepted Answer

For the same gas u av ∝ √(T), so u X = 2u Y ⇒ T X = 4T Y . Pressure P = nRT/V: P X = (1)R(4T)/1 = 4RT, P Y = (1)RT/2 = RT/2. Ratio P X /P Y = 4/(1/2) = 8. Confirms Ans (d) 8 times of that in Y.
