Consider a cooker without cover that holds 1000 ml of water at 25C and lbar. Heat is supplied to the cooker at a rate of 900W while pressure remains constant. After a period of time, the boiling point of water is reached and it continues to boil until all of the water has evaporated. Assuming the kinetic and potential energies of the streams are negligible. Determine: (8 points) 1.The work done by the system in kJ?
2.The time needed for the evaporation process to start in min?
3.The time needed for all of the water to convert to vapor in min?​
