Plan and design experiement

  1. Dec 10, 2011 #1
    Hypothesis: The hottest part of the flame can be found at x located just above the unburn gas.

    Aim: To investigate how the temperature of a flame varies with the height of the top of the burner.

    Help please getting alot of trouble with method and how to obtain results.

    Physicskid12: Welcome to Physics Forums. Here you can expect useful answers to your questions from professional scientists and engineers.

    For measuring flame temperature I suggest using a non-contact infrared thermometer. See:

    After a quick Google search I saw many selling for less than US$ 50.00. Note: You must select one that has a small “look angle” or small angular resolution. That means it must read temperature of a very small spot in order to measure different points in a single flame. Otherwise you could rig an opaque “pinhole mask” (tinfoil?), move it slowly across the flame, and take measurements. Then you could use any old non-contact thermometer.
