## Homework Statement

[/B]

Two balloons with Helium gas are filled, first with 10 liters of He and second with 20 liters. Molecules of which balloon will be moving faster as compared to the other?

## Homework Equations

## The Attempt at a Solution

Speed of molecules is directly proportional to temperature . Consider the fact that pressure inside balloon is same as ambient pressure i.e pressure is constant ( Atm. pressure) . Applying Ideal gas law PV = nRT ,temperature depends on 'n' and V . Volume is given but , 'n' is not given .

Is the question incomplete or am I missing something ?

Many Thanks
