Water of mass 3kg initially at 20℃ is heated in an electric kettle rated 3.0kW. Thewater is heated until it boils at 100℃. Taking specific heat capacity of water=4200Jkg/K, heat capacity of kettle=450J/kg, specific latent heat of vapourisation of water =2.3MJ/kg, calculate;

- The heat absorbed by the water.
- Heat absorbed by the electric kettle.
- The time taken for the water to boil .
- How much longer it will take to boil away all the water?
