Question

A system goes from A to B via two processes I and II as shown in figure. If capital delta U subscript 1 end subscript and capital delta U subscript 2 end subscript are the changes in internal energies in the processes I and II respectively, then

  1. capital delta U subscript text II end text end subscript greater than capital delta U subscript I end subscript    
  2. capital delta U subscript text II end text end subscript less than capital delta U subscript I end subscript    
  3. capital delta U subscript I end subscript equals capital delta U subscript text II end text end subscript    
  4. Relation between capital delta U subscript I end subscript and capital delta U subscript text II end text end subscript can not be determined    

The correct answer is: capital delta U subscript I end subscript equals capital delta U subscript text II end text end subscript


    As internal energy is a point function therefore change in internal energy does not depends upon the path followed i.e. capital delta U subscript I end subscript equals capital delta U subscript text II end text end subscript

    Following figure shows on adiabatic cylindrical container of volume V subscript 0 end subscript divided by an adiabatic smooth piston (area of cross-section = A) in two equal parts. An ideal gas left parenthesis C subscript P end subscript divided by C subscript V end subscript equals gamma right parenthesis is at pressure P1 and temperature T1 in left part and gas at pressure P2 and temperature T2 in right part. The piston is slowly displaced and released at a position where it can stay in equilibrium. The final pressure of the two parts will be (Suppose x = displacement of the piston)

Initially each of the two chambers of the box has one mole of monatomic ideal gas (gamma =5/(c) at a pressureP subscript 0 end subscript, volumeV subscript 0 end subscript and temperatureT subscript 0 end subscript. The chamber on the left is slowly heated by an electric heater. The walls of the box and the partition are thermally insulated. The gas in the left chamber expands, pushing the partition until the final pressure in both chambers becomes (243/3(b) P subscript 0 end subscript. The final temperature of the gas in left chamber is:
