Water of mass 6kg initially at 25°C is heated in an electric kettle rated 6.0Kw. The water is heated until it boils at 100°C.
(Take specific heat capacity of water 4200J/kg/k, heat capacity of the kettle 450J/k, specific latent heat of vaporisation
of water = 2.3 × 10⁶ J/kg)
Determine
i) Heat absorbed by the water.
ii) Heat absorbed by the electric kettle.
iii) Time taken for the water to boil.
iv) How much longer it will take to boil away all the water?
