Question

this graph shows the results of an investigation in which the scientist was studying the effect of salt on the boiling temperature of water. what is the dependent variable in this experiment?

amount of salt/g	boiling point of water/degrees c
0	100	100.5	100	100
5	105	104	105	105
10	109	109	110	109
15	118	117	119	118

options: time, temperature, amount of salt

Explanation:

In an experiment, the dependent variable is what is measured and depends on the independent variable. Here, the independent variable is the amount of salt (changed by the scientist), and the boiling point (temperature) of water is measured as it depends on the salt amount. Time isn't part of the experiment's variables here.

Answer:

Temperature
