Two closed bulbs of equal volume (V) containing an ideal gas initially at pressure Pi and temperature T1 are connected through a narrow tube of negligible volume as shown in the figure below. The temperature of one of the bulbs is then raised to T2. The final pressure Pf is (OJEE 2016) (a) i T 2P T T (b) i T 2P T T (c) i T T 2P T T (d) i T T P T T
Answer
B
Explanation
Number of particles in system 1= system 2. i.e. ' ' 1 2 1 2 n n n n Also the given volume for two systems is equal. PV nRT / n PV RT Therefore, 1 1 1 2 1 2 1 1 2 / / / / 2 >> i i f f f i PV RT PV RT P V RT P V RT P V PV T T RT R T T 2 1 2 2 i f PT P T T
