An immersion heater has a thermostat to control the water temperature in a hot water tank. When the temperature of the water inside the tank reaches 58°C the thermostat switches the heater off. The thermostat switches the heater back on when the temperature of the water falls to 50°C. The graph shows how the temperature of the water inside a hot water tank changes with time. The tank is not insulated. Which of the following gives the best explanation why the temperature of the water falls at the fastest rate just after the heater switches off?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
