8analyze. which variable changes in the investigation depicted in the drawing

9 conclude

10 infer

Given the figure above, there are two systems. One is heating water placed in a beaker, the other is heating salt water placed in a beaker with the same volume as the first one. Throughout the experiment, it can be assumed that the temperature is constant for both systems. The variable that changes is the concentration of each system. System A is water, thus the concentration is zero and system B is salt water, thus the concentration is more than zero. The data that can be collected is concentration vs volume vs time. 

Biased means unfair but that's all ik
