Detailed explanation-1: -The independent variable is the salt added in the water, whereas the dependent variable is the boiling point of the water. b. There will be three groups in this experiment. Both of the groups would have the same amount of water.
Detailed explanation-2: -The independent variable (also known as manipulated variable) is the amount of salt in water. The amount of salt in water may be reported as the percent of salt in water or as grams of salt per liter of water. The dependent variable (also known as responding variable) is the freezing point of water.
Detailed explanation-3: -CONCLUSION-Our hypothesis was if the heat energy in the water decreases, then the water will freeze. After testing our hypothesis we concluded that our experiment was a success. By adding ice and salt to the beaker that our test tube was sitting in it made the water freeze.
