Final answer:
The temperature of a welding arc exceeds 1,100 degrees Fahrenheit, making the statement False. A welding arc can reach temperatures of about 6,000 degrees Fahrenheit, and a tungsten light bulb filament at 2,900 Kelvin equals 4,712 degrees Fahrenheit and 2,626.85 degrees Celsius.
Step-by-step explanation:
The statement that the temperature of a welding arc does not exceed 1,100 degrees Fahrenheit is False. A welding arc generates temperatures that can reach approximately 6,000 degrees Fahrenheit or even higher to melt or fuse metal surfaces. This is significantly higher than the temperature described in the question. As for the filament of a tungsten light bulb, it operates at 2,900 Kelvin, which, when converted, is about 4,712 degrees Fahrenheit. On the Celsius scale, this temperature translates to approximately 2,626.85 degrees Celsius.
