Physics - Heat & Thermo Question with Solution | TestHub

Three bodies A, B, C of masses $m$, $m$ and $\sqrt{3}m$ are supplied heat at a same rate. The change in temperature ($\theta$) versus time graph for A, B, C is as shown. If the specific heats are $s_A$, $s_B$ and $s_C$, then which of the following is correct? (Initial temperature of bodies are $0^{\circ }\mathrm{C}$)
