Sarah wanted to know if water boils faster when salt is added to it. She put two liters of water in two identical pots, then added three tablespoons of salt to one pot. She put both pots on a stove, each on high heat, and recorded how long it took for the water to boil. If Sarah had used different amounts of water in the two pots, how might this affect her results?

C) She wouldn't know if the faster time was the result of the amount of salt or the amount of water in the pot.
