Question

The P-V diagram shows seven curved paths (connected by vertical paths) that can be followed by a gas. Which two of them should be parts of a closed cycle if the net work done by the gas is to be at its maximum

  1. ac    
  2. cg    
  3. af    
  4. cd    

The correct answer is: af


    Area enclosed between a and f is maximum. So work done in closed cycles follows a and f is maximum.

    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)

    A cylindrical tube of uniform cross-sectional area A is fitted with two air tight frictionless pistons. The pistons are connected to each other by a metallic wire. Initially the pressure of the gas is P0 and temperature is T0, atmospheric pressure is also P0. Now the temperature of the gas is increased to 2T0, the tension in the wire will be
