Question

Complete the following data sheet: Specific heat of the material of the calorimeter, s = 0.093 cal/(gm middot C degree ) Water equivalent of the heating coil, stirrer, etc.. m 3 = 6.8 gm Mass of the empty dry calorimeter. m1 = 123.4 gm Mass of calorimeter plus water, m = 280.1 gm Mass of water in the calorimeter, m2 = Length of a time interval, t = Total average power. P = Total electrical energy supplied. W = Initial temperature. T1 = 22.6 degree C Final temperature. T2 = 28.2 degree C Amount of heat generated in calories. H = Joule's Constant. J = Percent error in J (standard value is equal to 4.186 J/cal) = Give values for all missing items on the sheet. Give Power = {P1, P2. P3, P4. P5} Give Average Power = {AP1, AP2, AP3, AP4}

Explanation / Answer

m2 = 149.9 gm For the power part : Electrical current, measured in amperes, is the time rate of flow of electrical charge (coulombs); by definition, The common relationships between electrical potential in volts (V), current in amperes (I), and resistance in ohms (R) is known as Ohm’s Law, V = IR Electrical energy is given by E = I^2 Rt volt coulombs By definition: l joule = l volt coulomb By combining these laws and definitions, we get Electrical energy = I^2 Rt joules
