1. The problem statement, all variables and given/known data Part a. A 500 W kettle contains 300g of water at 20°C. Calculate the time it would take to raise the temperature of the water to boiling point. Part b. The kettle is allowed to boil for 2 minutes. Calculate the mass of water that would remain in the kettle. State any assumptions you make. (Specific heat capacity of water = 4.18x103 J kg-1 °C-1, specific latent heat of vaporisation of water = 2.26x106 J kg-1.) 2. The attempt at a solution I have the answer for part a. It's (rounded) about 201 seconds. Problem: I don't know where to start from for part b. Someone help.
