1) Complete the table below for H2O. 2) 40-L electrical radiator containing heating oil is placed in a 50m3 room. Both the room and the oil in the radiator are initially at 10C. The radiator with a rating of 2.4kW is now turned on. At the same time, heat is lost from the room at an average rate of 0.35 kJ/s. After some time, the average temperature is measured to be 20C for the air in the room, and 50C for the oil in the radiator. Taking the density and the specific heat of the oil to be 950kg/m3 and 2.2kJ/kgC, respectively, determine how long the heater is kept on. Assume the room is well-sealed so that there are no air leaks
