Question

In the following p minus V diagram figure two adiabates cut two isothermals at T subscript 1 end subscript and T subscript 2 end subscript. The value of V subscript b end subscript divided by V subscript c end subscript is

  1. equals V subscript a end subscript divided by V subscript d end subscript    
  2. less than V subscript a end subscript divided by V subscript d end subscript    
  3. greater than V subscript a end subscript divided by V subscript d end subscript    
  4. Cannot say    

The correct answer is: equals V subscript a end subscript divided by V subscript d end subscript


    From symmetry considerations and also from theory,
    fraction numerator V subscript a end subscript over denominator V subscript d end subscript end fraction equals fraction numerator V subscript b end subscript over denominator V subscript c end subscript end fraction
