In summary, for an investigation on how the temperature of a flame changes with the height of the burner, it is recommended to use a non-contact infrared thermometer with a small "look angle" or angular resolution. These can be found for less than $50 and will allow for accurate measurements at different points in a flame. Alternatively, a homemade "pinhole mask" can be used with a regular non-contact thermometer.

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 a lot 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.
 

FAQ: What is the most effective way to measure flame temperature?

What is the purpose of planning and designing an experiment?

The purpose of planning and designing an experiment is to ensure that the experiment is well-structured and organized, with a clear objective and methodology. This helps to minimize errors and bias, and to obtain reliable and accurate results.

What are the key elements of an experimental design?

The key elements of an experimental design include the independent and dependent variables, control group, experimental group, randomization, and replication. These elements help to ensure that the experiment is controlled and that any observed effects can be attributed to the independent variable.

How do you determine the sample size for an experiment?

The sample size for an experiment can be determined by conducting a power analysis. This involves considering factors such as the desired effect size, level of significance, and statistical power. A larger sample size is generally preferred as it increases the chances of detecting a significant effect.

What is the difference between a controlled experiment and an observational study?

A controlled experiment involves manipulating the independent variable to observe its effect on the dependent variable, while keeping all other variables constant. In contrast, an observational study involves observing and recording naturally occurring behaviors or phenomena without any manipulation. Controlled experiments are considered more reliable for establishing cause-and-effect relationships.

How do you ensure the validity and reliability of an experiment?

To ensure validity, the experiment should be designed to minimize any sources of bias and to accurately measure the intended variable. This can be achieved through randomization, blinding, and using appropriate measurement tools. To ensure reliability, the experiment should be replicable and produce consistent results when repeated. This can be achieved by clearly documenting the methodology and procedures used.
