Cooling curves are drawn for three liquids a,b,c, shown in fig. for which liquid specific heat is least?

Equal masses of three liquids are thoroughly mixed. The specific heat capacities of the liquids ar s_(1), s_(2) and s_(3) and their temperatures t_(1), t_(2) and t_(3) respectively. Find the temperature of the mixture.

A "flow calorimeter" is used to measure the specific heat of a liquid. Heat is added at a known rate to a stream of the liquid as it passes through the calorimeter at known rate, then a measurement of the resulting temperature difference between the in flow and the out flow points of the liquid stream enables us to compute the specific heat of the liquid. A liquid of density 0.85 g//cm^(3) flows through a calorimeter at the rate of 8.0 cm^(3)//s . heat is added by means of a 250 watt electric heating coil, and a temperature difference of 15^(@)C is established in steady state conditions between the in flow and out flow points. Q. Specific heat of the liquid is
