How long does it take to boil a kettle dry?A student boiled 1 ltr of water in a kettle while measuring the temperature with a temperature sensor. Using the information from the temperature vs time graph, estimate how long would it take for the kettle to boil dry.
Specific heat capacity of water = 4200 Jkg-1K-1
Specific Latent heat of vapourisation of water = 2.2 x 106 Jkg-1
