A bulb 'X' of unknown volume containing a gas at one atmospheric pressure is connected to an evacuated bulb of 0.5 litre capacity through a stop -cock. On opening the stop-cock, the pressure in the whole system after some time was found to have a constant value of 570 mm at the same temperature. What is the volume of the bulb X ?

Answer

A

Explanation

Suppose volume of the bulb X=V, i.e., `V_(1)`=V and `P_(1)`=1 atm
After connecting to bulb of 0.5 L capacity, volume =(V+0.5 L)
i.e., `" " V_(2)=(V+0.5) L, P_(2)=570 mm=570//760" atm"`
Apply `" "P_(1)V_(1)=P_(2)V_(2)`, calculate V.
