Question

Which of the substance A comma blank B or C has the highest specific heat? The temperature v s time graph is shown

  1. A    
  2. B    
  3. C    
  4. All have equal specific heat    

The correct answer is: C


    Substances having more specific heat take longer time to get heated to a higher temperature and longer time to get cooled.

    If we draw a line parallel to the time axis then it cuts the given graphs at three different points. Corresponding points on the times axis shows that
    t subscript C end subscript greater than t subscript B end subscript greater than t subscript A end subscript rightwards double arrow C subscript C end subscript greater than C subscript B end subscript greater than C subscript A end subscript
