Answer: The correct answer is mass is the independent variable, and boiling point is the dependent variable.
Explanation:
Dependent variable is defined as the variable whose value changes with respect to any other variable.
Independent variable is defined as the variable which remain as such and has no effect on the change of another variable. For Example: Time
According to the question:
We examine the effect of adding different amounts of salt on the boiling point of water.
As, the amount of salt increases, it further increases the boiling point of water because impurities are getting add up in pure water.
Thus, amount of salt is an independent quantity and boiling point of water is the dependent quantity.
