In a certain system of units, the fundamental unit of mass is taken as $2 \mathrm{kg},$ unit of length is taken as $\frac{1}{2} \mathrm{m},$ unit of time taken as $4 \mathrm{s}$ and unit of temperature is taken as $2$ Kelvin.

Two identical systems, with heat capacity at constant volume that varies as $C_v=b{T}^3$ (where $b$ is a constant) are thermally isolated. Initially, one system is at a temperature $100\mathrm{ }\mathrm{K}$ and the other is at $200 \mathrm{K}$ .
