Question

An ideal gas of mass m in a state A goes to another state B via three different processes as shown in figure. If Q subscript 1 end subscript comma Q subscript 2 end subscript and Q subscript 3 end subscript denote the heat absorbed by the gas along the three paths, then

  1. Q subscript 1 end subscript less than Q subscript 2 end subscript less than Q subscript 3 end subscript    
  2. Q subscript 1 end subscript less than Q subscript 2 end subscript equals Q subscript 3 end subscript    
  3. Q subscript 1 end subscript equals Q subscript 2 end subscript greater than Q subscript 3 end subscript    
  4. Q subscript 1 end subscript greater than Q subscript 2 end subscript greater than Q subscript 3 end subscript    

The correct answer is: Q subscript 1 end subscript less than Q subscript 2 end subscript less than Q subscript 3 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)

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
