3 kg of liquid water initially at 12°C is to be heated at 95°C in a teapot equipped with a 1200-W electric heating element inside. The specific heat of water can be taken to be 4.18 kJ/kg - °C, and the heat loss from the water luring heating can be neglected. Solve for the time it takes to heat water to the desired temperature.
