Two bodies $A$ and $B$ of equal masses, area and emissivity cooling under Newton's law of cooling from same temperature are represented by the graph. If $\theta$ is the instantaneous temperature of the body and $\theta_0$ is the temperature of surroundings, then relationship between their specific heats is ..........

A

$S_A=S_b$

B

$S_A > S_b$

C

$S_A < S_b$

D

None of these

Solution

(b)

Body loosing its temperature soon means low specific heat

$\Rightarrow S_A > S_B$
