366321 A thermally insulated vessel contains two liquids at temperatures \(T_{1}\) and \(T_{2}\) respectively and specific heats \(c_{1}\) and \(c_{2}\) separated by a non-conducting partition. The partition is removed and the difference between the initial temperature of one of the liquids and the temperature \(T\) established in the vessel turns out to be equal to half the difference between the initial temperature of the liquids. Determine the ratio \(\dfrac{m_{1}}{m_{2}}\) (massess of the liquids)

1 \(\dfrac{c_{2}}{c_{1}}\)
2 \(\dfrac{c_{2}+c_{1}}{c_{2}-c_{1}}\)
3 \(\dfrac{c_{2}-c_{1}}{c_{2}+c_{1}}\)
4 \(\dfrac{2 c_{1}-c_{2}}{c_{2}+c_{1}}\)
