i need help finding what would go on the x-axis or the y-axis?

Question

i did a lab about evaporattion and intermolecular attractions...and we tested 4 chemicals: methanol, ethanol, propanol. butanol....and we tested their initial temp and then final temp...so we found the change in temp..

and we caculated their molar mass and the # of electorns in each molecule..

so now i have to graph

change in temp......vs....# of electrons
and
change in temp.....vs....molar mass

they are 2 seperate graphs

i need to know which items go where
like what axis does each go on??

help???


i hate chem..

Answer 1

Temperature would go on the x-axis in both situations because it is the independent variable. For example... the number of electrons depends on the temperature.

Answer 2

You don't have to hate chemistry because you have to plot a graph. Graphs are plotted to represent, corelate and present results or data in a schematic or pictorial form, in any subject. This is with the aim of making the data more comprehendable and that too at a glance.

The parameter that goes on the X axis is always the independent parameter i.e. whose value does not depend upon the value of the other parameter. In the present case, Temperature is the independent parameter (and hence goes on the X axis) as it does not depend upon molecular attraction but rather decides the latters extent.

Answer 3

The independent variable always goes on the "X" axis. That is the variable that you changed during the reaction.

The dependent variable always goes on the "Y" axis. That is the one that changed DUE TO a change in the independent.

independent = # e- on graph one and molar mass on graph two.

dependent = change in temp for both graphs.
