### Two closed bulbs of equal volume (V) containing an ideal gas initially at pressure Pi and temperature Ti are connected through a narrow tube of negligible volume as shown in the figure below. The pressure of one of the bulb is raised to T2. The final pressure is: (JEE Mains-2016)

Initially both bulbs are under similar condition hence number of moles of gas in each container

Total number of moles in both bulbs;

When temperature of one of the bulb is increases from T1 toT2 then final pressure Pf  and number of moles.

But total moles cannot be affected on increasing temperature. hence number of moles before and after increasing temperature is remain same. from equation (1) and (2)
