Question description

Complete the following data sheet:

Specific heat of the material of the calorimeter, s = 0.093 cal/(gm ⋅ C°)
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 =

No.Time (min)Temperature (C °)Voltage (V)Current (A)Power (watt)
1022.65.21.1
2324.15.11.1
3625.45.21.2
4926.85.01.0
51227.85.21.1

Interval No.Time Interval (min)Average Power (watt)
10 - 3
23 - 6
36 - 9
49 - 12

Length of a time interval, t = 
Total average power, P = Total electrical energy supplied, W = 
Initial temperature, T1 = 22.6 °C
Final temperature, T2 = 28.2 °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}
