QUESTION 3 Insulated container Nichrome heater Figure 2 Based on the manufacturer's details, a heater is made of pure nichrome with 3.0 kg mass. The water container is insulated and has a maximum capacity of 100 kg of water. A group of scientists tasked to conduct experiments on the heater. Equipment, tools and utilities starts with temperature of 25°C. The scientists used these as reference: Specific heat capacity of nichrome = 450 J.kg-1.°C-1, Specific heat capacity of water = 4182 J.kg-¹.°C-1. a) The heater was connected to an electric point without any water in it. Using electric regulator, 5000 kJ of energy was used and converted into heat by the heater. Assuming there is no energy leakage, what is the expected new temperature of the heater? (CO3, PO1, C3) b) 100 kg of water with temperature of 25°C was then poured into the insulated container with the heater submerged in it.
