In similar calorimeters, equal volumes of water and alcohol, when poured, take \(100\,\sec \) and 74 sec respectively, to cool from \(50^{\circ} C\) to \(40^{\circ} C\). If the thermal capacity of each calorimeter is numerically equal to volume of either liquid, then calculate the specific heat capacity of alcohol (given: the relative density of alcohol as 0.8 and specific heat capacity of water as
1 cal g \(\left.{ }^{-10} C^{-1}\right)\).
366288 A chef, on finding his stove out of order, decides to boil coffee by shaking it in a thermosflask. Suppose that he uses water at \(15^\circ C\) and that the water falls \(30\;cm\) each shake, the chef making 30 shakes each minute. Neglecting any loss of thermal energy by the flask, how long must he shake the flask until the water reaches \(100^\circ C\left( {{c_{{\rm{coffee }}}} = 4190\;J} \right)\) ?
