For the following questions, assume the latent heat of vaporisation for water is Lu - 2.260 x 106 J/kg and the specific heat capacity of water is Cu = 4184 J/kg/K. a) A student has a kettle filled with 1.44 Litres of water. The power of the kettle is P - 1700W and the water has just finished boiling (i.e., it is at 100C). A student holds down the button so that the kettle remains on, and the water continues to boil (and eventually boils away). If they hold it on for t - 104 seconds, what is the volume of water remaining in the kettle? V b) The remaining water (i.e., the amount of water you calculated in part a) is left to cool to room temperature, which is Troom. = 23. C. How much heat energy leaves the water during this process? (Your answer should be a positive number) Q c) By which mechanism is: The water directly in contact with the heating element heated? (No answer given) The water not directly in contact with the heating element, but in the kettle, heated? (No answer given) +
