1. The units are:

      a) temperature: degree Celcius: ºC

      b) heat: Joule: J

      c) specific heat capacity: J/kg ºC

      d) specific latent heat: J/kg

  2. Energy transferred = mass x specific heat capacity x temperature change

      Energy transferred = 1 x 4200 x 75

      Energy transferred = 315 000 J

  3. Energy transferred = mass x specific latent heat

      Energy transferred = 1 x 340 000

      Energy transferred = 340 000 J
