Answer:
Does the nature of intermolecular forces present in different substance affect their boiling points?
Explanation:
In every scientific research there must be a dependent and an independent variable. These variables are easily deduced from the scientific question that is being investigated.
If a student is comparing the boiling points of different substances having different intermolecular forces, then his or her aim is to establish a relationship between the nature of intermolecular forces present (independent variable) and the observed boiling point of the substance (dependent variable).
This is aptly shown by the research question ' Does the nature of intermolecular forces present in different substance affect their boiling points?'
