Think Like a Scientist: Comparing Boiling Points

Task:
Plan a test to compare the boiling points of different substances.

Instructions:
1. Work in a group to plan a fair test.

Questions to Consider:
1. In your test, which variables will you:
- Change (independent variable)?
- Keep the same (constant variables)?
- Measure (dependent variable)?

2. What materials and equipment will you need?

3. What will you do to compare the boiling points of the different substances?

4. Are there any dangers or risks in your investigation? How will you work safely?

5. How will you record and present your results?

Final answer:

The answer provides guidance on planning a test to compare boiling points of substances including variables, materials needed, and procedures.


Explanation:

Designing a Test to Compare Boiling Points of Substances:

  1. Independent Variable: The substance being tested.
  2. Constant Variables: Heating rate, volume of substances, atmospheric pressure.
  3. Measure: Boiling point of each substance.

Materials and Equipment:

  • Test tubes, Bunsen burners, test tube holders, safety goggles, substances to test.

Procedure:

  1. Heat each substance and record boiling points.
  2. Ensure safety by using safety equipment and proper handling.
  3. Record results and present findings in a comparative manner.
