In this \((P-V)\) diagram below the dashed curved line is adiabatic.

                       
For a process, that is described by a straight line joining two points \(X\) and \(Y\) on the adiabat (solid line In the diagram) heat is:
(Consider the variations in temperature from \(X\) to \(Y\) along the straight line.)

1. absorbed throughout from \(X\) to \(Y.\)
2. released throughout from \(X\) to \(Y.\)
3. absorbed from \(X\) up to an intermediate point \(Z\) (not shown In the figure) and then released from \(Z\) to \(Y.\)
4. released from \(X\) up to an Intermediate point \(Z\) (not shown in the figure) and then absorbed from \(Z\) to \(Y.\)

An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric, and isochoric. The curve which represents the adiabatic process among \(1,\) \(2,\) \(3\) and \(4\) is: 
          
1. \(4\) 2. \(1\)
3. \(2\) 4. \(3\)

Match the thermodynamic processes taking place in a system with the correct conditions. In the table, \(\Delta Q\) is the heat supplied, \(\Delta W\) is the work done and \(\Delta U\) is the change in internal energy of the system.

Process Condition
(I) Adiabatic (A) \(\Delta W=0\)
(II) Isothermal (B) \(\Delta Q=0\)
(III) Isochoric (C) \(\Delta U\neq0, \Delta W\neq0,\Delta Q\neq0\)
(IV) Isobaric (D) \(\Delta U=0\)
 
1. (I) – (B), (II) – (A), (III) – (D), (IV) – (C)
2. (I) – (A), (II) – (A), (III) – (B), (IV) – (C)
