Question 17Refrigeration/AC - QMED70% to pass
What is the color of the flame produced by a halide torch when there is no halogenated refrigerant present at the location of the exploring tube?
AI Explanation
The correct answer is C) blue.
When a halide torch is used in the absence of halogenated refrigerants, the flame produced will be blue in color. This is because the blue flame is produced by the combustion of the gas used in the torch, typically propane or butane, without any interference from halogenated compounds.
The other answer choices are incorrect because purple, green, and orange flames are not the expected color when there are no halogenated refrigerants present. The presence of different elements or compounds in the environment can cause the flame to change color, but in the absence of halogenated refrigerants, the flame will remain blue.
