A calorimeter of water equivalent \[5\times {{10}^{-3}}\text{ }kg\] contains \[25\times {{10}^{-3}}\text{ }kg\] of water. It takes 3 minutes to cool from \[28{}^\circ C\] to \[21{}^\circ C\]. When the same calorimeter is filled with \[30\times {{10}^{-3}}\text{ }kg\] of turpentine oil then it takes 2 minutes to cool from \[28{}^\circ C\] to \[21{}^\circ C\]. Find out the specific heat (in \[cal/g{}^\circ C\]) of turpentine oil.
