Two circular discs A and B with equal radii are blackened. They are heated to same temperature and are cooled under identical conditions. What inference do you draw from their cooling curves ?
A
A and B have same specific heats
B
Specific heat of A is less
C
Specific heat of B is less
D
Nothing can be said
Answer
Specific heat of A is less
Explanation
Solution
R µ (q – q0) cooling is poster for A than B. so specific heat of A is smaller than B.
