Two flasks X and Y have capacity 1 and 3 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 three times as those in Y. The pressure in flask X would be
Options:
Answer:
D
Solution:
Same gas, uav ∝ √(T): uX = 3uY ⇒ TX = 9TY. Pressures: PX = (1)R(9T)/1 = 9RT, PY = (1)RT/3. Ratio = 9/(1/3) = 27. Confirms Ans (d) 27 times of that in Y.
