In an experiment to determine the specific latent heat of vaporisation of water, a student recorded the following measurements:

  • Initial mass of the beaker and water = 0.125 kg0.125\text{ kg}0.125 kg
  • Final mass of the beaker and water = 0.113 kg0.113\text{ kg}0.113 kg
  • Energy transferred by the immersion heater while the water boiled = 27 120 J27\,120\text{ J}27120 J

Calculate the specific latent heat of vaporisation of water from this data. State the correct unit with your answer.
