The total volume of the water tank used in the equipment is 0.02 m3", and the water is heated through the heating rod. The efficiency of the water circulator 40W is 40%, and the remaining energy is released as heat. Given that the heat lost in the entire area in contact with the outside is KI(T-Ta)dT, find the following. O 25 °C → 30 °C. 2 30 °C → 35 °C (C.=4.184J/ml-C, Ta=20 °C. K = 10 J/s-C) (1) Energy balance: equation (2) Total energy used by Heating rod (J)
