Two flasks X and Y have capacity 1 L and 2 L respectively and each of them contains 1 mole of a gas. The temperatures of the flasks are so adjusted that average speed of molecules in X is twice as those in Y The pressure in flask X would be
(a) same as that in Y
(b) half of that in Y
(c) twice of that in Y
(d) 8 times of that in Y.
