A vessel A has volume V and a vessel B has volume 2V. Both contain some water which has a constant volume. The pressure in the space above water is p_a for vessel A and p_b for vessel B.
(a) p_a = p_b
(b) p_a = 2p_b
(c) p_b = 2p_a
(d) p_b = 4p_a
digAnsr: a
Ans : The maximum pressure attainable above the water will be saturated vapour pressure at that temperature. Since saturated vapour pressure does not depend upon volume, both the vessels will have same pressure.
Thus,
(a) is the correct answer.
