An electric kettle with a 2.0kw heating element has a heat capacity of 400j/k. 1.0kg of water at 20°C is placed in the kettle. The kettle is switches on and it is found that 13 minutes later the mass of water in it is 0.5kg. Ignoring heat losses ; calculate
i) Total heat supplied.
ii) Heat used for the kettle.
iii) Heat used to raise temperature of 1kg of water from 20°C to 100°C.
iv) Heat to change water at 100°C to steam at 100°C.
v) The specific latent heat of vaporization of water.
