Question

The diagram shows the change x in the length of a thin uniform wire caused by the application of stress F at two different temperatures T subscript 1 end subscriptand T subscript 2 end subscript. The variation shown suggest that

  1. T subscript 1 end subscript greater than T subscript 2 end subscript    
  2. T subscript 1 end subscript less than T subscript 2 end subscript    
  3. T subscript 1 end subscript equals T subscript 2 end subscript    
  4. None of these    

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


    Elasticity of wire decreases at high temperature i. e. at higher temperature slope of graph will be less
    So we can say that T subscript 1 end subscript greater than T subscript 2 end subscript
