A flow calorimeter is used to measure the specific heat of a liquid. Heat is added at a known rate to a steam of the liquid as it passes through the calorimeter at a known rate. Then a measurement of the resulting temperature difference between the inflow and the outflow points of the liquid stream enables us to compute the specific heat of the liquid. A liquid of density 0.85 g.cm3 flows through a calorimeter at the rate of 8.2 cm3/s. Heat is added by means of a 250-W electric heating coil, and a temperature difference of 15 Cº is established in steady state conditions between the inflow and the outflow points. Find the specific heat of the liquid.
