Question

The temperatures towards the end of the experiment do not change very much. Why is this?

Answer 1

Answer:

An experiment is carried out to demonstrate the effect of independent variable on a dependant variable. During an experiment, scientists must prevent outside influences, known as confounding variables, from altering the results. When a scientist actively decides to limit the impact of a confounding variable, it becomes known as a control variable instead. Although it is not always a confounding variable in experiments, scientists will often choose to control the variable of temperature by holding it constant.
