Question
Which of the substances A, B or C has the highest specific heat ? The temperature vs time graph is shown
- A
- B
- C
- 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
