Physics - Heat & Thermo Question with Solution | TestHub

A thermally insulated vessel contains two liquids A & B with initial temperatures ${\mathrm{T}}_1$ & ${\mathrm{T}}_2$ and specific heats ${\mathrm{s}}_1$ & ${\mathrm{s}}_2$ respectively. They are separated by a non-conducting piston. When the partition is removed the final equilibrium temperature is average of the initial temperatures of the liquids. The ratio of masses of two liquids ${\mathrm{m}}_1/{\mathrm{m}}_2$ is :
