Method

  1. Measure the temperature of the water with a thermometer
  2. Finally Repeat the experiment using different temperatures of water.
  3. First Measure 100 cm3 of water using a measuring cylinder
  4. Measure the mass of the water and beaker with a mass balance
  5. Calculate the mass of salt using mass of salt water in beaker - mass of water in beaker
  6. Measure the mass of the salt solution with a mass balance
  7. Add potassium chloride until no more will dissolve
  8. Add the water to the beaker
