The aspect of the experiment that is missing from the experimental design for the determination of the boiling points of water and ethanol is deciding on the appropriate equipment.
The correct option is C.
<h3>What are experiments?</h3>
Experiments are scientific procedures that are designed to test a hypothesis in order to prove or disprove the hypothesis.
Also, experiments are done to make discoveries as well as to repeat or confirm a fact.
In designing an experiment, the following components of the experimental design are necessary:
- determining the procedure
- determining what data to collect
- deciding on the appropriate equipment
- deciding on the number of trials to perform
For example, in an experiment to determine the boiling points of water and ethanol, appropriate equipment such as a thermometer is needed.
