Answer is Wrong!
Answer is Right!
The correct answer is: C. 3600°C
Oxy-acetylene flame is a very hot flame that is used for welding and cutting metals. It is created by mixing oxygen and acetylene gases and then igniting them. The temperature of the flame can reach up to 3600°C, which is hot enough to melt most metals.
The other options are incorrect because they are not as hot as 3600°C. Option A is 2800°C, option B is 3200°C, and option D is 4000°C.
Oxy-acetylene flame is a very powerful tool that can be used for a variety of purposes. It is important to use it safely and responsibly.
