Question

A student measured the maximum mass of salt that can dissolve in 100mL of water at five different temperatures. Which variable should go on the x-axis?
A: the volume of water
B: the temperature of water
C: the mass of water
D: the mass of salt ​

Answer 1

Answer: The answer is B, The variable that should go on the x- axis is the temperature of water.

Explanation: In an experiment, we must have two variables; the independent variable and the dependent variable.

If the results of the experiment is reported in graphical format, the independent variable is plotted on the x axis while the dependent variable is plotted on the y axis.

In this case, the independent variable is the temperature of the water while the dependent variable is the mass of salt dissolved in 100 mL of water.

Therefore, the variable that should go on the x- axis is the temperature of water.
