Water is boiled at sea level in a coffeemaker equipped with an

immersion-type electric heating element. The coffeemaker contains 1L of water when full. Once boiling starts, it is observed that half of the water in the coffeemaker evaporates in 13 min. Determine the power rating of the electric heating element immersed in water. Also, determine how long it will take for this heater to raise the temperature of 1 L of cold water from 18°C to the boiling temperature.
