\( 200 \mathrm{~g} \) of water and equal volume of another liquid of mass \( 250 \mathrm{~g} \) are placed in turn in the same calorimeter of mass \( 100 \mathrm{~g} \) and specific heat capacity \( 420 \mathrm{~J} / \mathrm{kgK} \). The liquids which are constantly stirred are found to cool from \( 60^{\circ} \mathrm{C} \) to \( 20^{\circ} \mathrm{C} \) in 3 minutes and 2 minutes 20 seconds, respectively. Find the
\( \mathrm{P} \) specific heat capacity of the liquid. The temperature of the surroundings is \( 20^{\circ} \mathrm{C} \).
