Photoelectric EffectHard
Question
Two balloons are filled one with pure.He gas and the by air respectively.If the pressure and temperature of these baloons are same than the number of molecles per unit volume is
Options
A.More in the He filled balloon
B.same in both balloons
C.more in air filled ballon
D.in the ratio of 1 : 4
Solution
We know that equal volume of different contain equal no. of molecules of sametemperature &pressure. So(b) will be the answer.
