Two circular discs A and B with equal radii are blackened. They are heated to same temperature and then cooled under identical conditions. What inference do you draw from their cooling curves as shown in figure?
R is rate of colling
R is rate of colling
- A and B have same specific heats
- specific heat of A is less
- specific heat of B is less
- nothing can be said
Answer
(C) specific heat of B is less
