Question

60 points! I am leaning toward C. Temperature

A student conducts an experiment to test how the temperature affects the amount of salt that can dissolve in water. In the experiment, she uses 150 milliliters of water in each trial and stirs for five minutes each time.

What is the independent variable in this experiment?

the amount of salt

the time stirred

the temperature of the water

the amount of water

Answer 1

C. Temperature of the water.

Step-by-step explanation:

An independent variable is defined as the variable which is not affected by any other variable in the experiment while also being the variable that is changed and controlled by only the student.

All other stated variables are constant variables, which remain completely unchanged throughout the experiment, in this case the time stirred and the amount of salt, and amount of water.
