An electric kettle has a power output of 2.3kW. The kettle is usedto heat a mass of 950g of water of specific heat capacity 4200J/kgK(i) Caclulate the time taken to heat the water from 15C to 100C(the answer is 147 seconds and I've already figured it out)(ii) The kettle is left switched on when the water temperaturereaches 100C. Calculate the rate at which the water is boiled away.(The specific latent heat of vaporization of water is 2.2MJ/kg
