Question

The plots which does not represent isothermal expansion of an ideal gas is:

  1. A
  2. B
  3. C
  4. D


Solution

The correct options are
B B
D D
For an isothermal expansion,
PVm=kso, P=k/Vm
where k is a constant.

graph A :
So here it means P is directly proportional to 1/Vm i.e
  P1Vm,  so graph A is correct.

graph B:
Since P1Vm so graph of P vs Vm should be parabolic in nature but it is given as a straight line so it is not correct.

graph C:
For isothermal expansion,
PVm= constant
graph C is also correct.

graph D:
As U is constant for an isothermal ideal gas expansion, hence graph D is incorrect

So incorrect graphs are B and D.

The correct graphs for B and D are given below.
