21) A student runs an experiment testing the effect of different amounts of salt on the boiling point temperature of water. In pot A she adds no salt (NaCl) to the water, in pot B she adds 20 g of NaCl, and in pot C she adds 40 g of NaCl. She boils each and finds that pot A boiled at 100 °C, pot B boiled at 102 °C, and pot C boiled at 104 °C. Identify the dependant variable, the independent variable, and 2 controlled variables.
