Water at temperature 25°C flows from a tap T into a heated container C. The container has a heating element (a resistor R) which is supplied with electrical power, P, that may be varied. The rate of flow of water F = 0.030 litres per minute. The electrical power is sufficient that C the water in the container is boiling. What is the minimum power that must be supplied in the steady state so that the amount of liquid water in R the container neither increases nor decreases with time? You may neglect other losses of heat, such as conduction and radiation from the container to the air.
