Question

I, II, and III are three isotherms, respectively, at T subscript 1 end subscript comma blank T subscript 2 end subscript comma blank and T subscript 3 end subscript. Temperature will be in order

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

The correct answer is: T subscript 1 end subscript greater than T subscript 2 end subscript greater than T subscript 3 end subscript


    Draw a line at constant P parallel to volume axis. Take volume corresponding to each temperature
    From volume axis, V subscript 1 end subscript greater than V subscript 2 end subscript greater than V subscript 3 end subscript
    Hence, T subscript 1 end subscript greater than T subscript 2 end subscript greater than T subscript 3 end subscript
