At what temperature does acetylene burn?

Acetylene burns at a temperature that can reach approximately 3,000 degrees Fahrenheit in air. This high flame temperature makes acetylene an ideal fuel for cutting and welding applications, as it can easily melt most metals. The combustion of acetylene produces a very high-temperature flame due to the energy released by its combustion reaction, which involves combining acetylene with oxygen.

In contrast, other temperatures listed do not match the typical characteristics of acetylene combustion. While other fuels may burn at these temperatures, the unique properties of acetylene, including its rapid combustion and high energy output, are specifically why it is often used in industrial settings where high temperatures are required.

Understanding the combustion temperature of acetylene is crucial for those working with this gas, as it informs safety practices and effective use in various applications like welding.
