Comparing Blue Flame vs Yellow Flame: Bunsen Burner Experiment

Design a fair test to determine if the blue flame is hotter than the yellow flame of a Bunsen burner. Formulate a hypothesis, predict outcomes, outline experiment set-up, clarify measurements, ensure fairness, and draw conclusions based on boiling water timing.

  1. Designing a fair test

  2. Blue flame? Yellow flame? Designing a fair test Which flame of the Bunsen burner is hotter?

  3. Designing a fair test 1 What is your hypothesis ? The blue flame isthan the yellow flame. hotter

  4. Designing a fair test 2 Based on your hypothesis, what is your prediction ? If the blue flame isthan the yellow flame,water will reach boiling. hotter faster

  5. Designing a fair test 3 You have the following apparatus.

  6. I will... Designing a fair test How will you carry out the experiment ? • heat water in a beaker with a flame until it boils, blue • heat water in another beaker with a flame until it boils. yellow

  7. Designing a fair test 4 What will you measure ? I will use a... to measure the time for the water in the two beakers to boil. stop-watch

  8. Designing a fair test 5 What will you do to make sure that the test is fair ? I will use Bunsen burner to boil the water in the two beakers. the same I will put amount of water at temperature into the two beakers. equal the same Same gas supply Stop timing as soon as the water boils.

  9. Designing a fair test 6 How will you draw your conclusion ? The flame that takes a shorter time to boil water is . hotter
