- Using graphing software such as Excel®, graph theresults of Activity 1. Please see the Introduction to Graphingmanual for guidance.
            a. What are the two variables that you graphed?
            b.Which is the independent variable? Should it be on the X- orY-axis? Why?
            c. Which is the dependent variable? Should it be on the X- orY-axis? Why?
Note: This a chemistry experiment, where we try to dissolve aAlka-Seltzer® tablet in 3 different temp of water. C =Cold , RT = Room temp, H = Hot. Then we record the time the tablettakes to dissolve in each cup of water (we do this 3 times for eachcup with different temp). I know that the independent variable isthe temp and the dependent variable is the time the tablet takes todissolve, but I do not know how to graph the data on Excel or whichneeds to be on the x or y axis.
