Did you know?
When looking at a flame's temperature there are many factors which can change or apply. An important one is that a flame's color does not necessarily determine a temperature comparison because black-body radiation is not the only thing that produces or determines the color seen; therefore it is only an estimation of temperature. Other factors that determine its temperature are: WebChemistry questions and answers. 1. a. What is the dominant color of a nonluminous flame from a Bunsen burner? Explain. b. Is the temperature of a luminous flame greater or less than that of a nonluminous flame? Explain 2. Diagram the cross section of a graduated cylinder, illustrating how to read the menineus 164 ba 3.
