Question

The temperature of oxy-acetylene flame is___________.
A. 200$^{o}C$
B. 1600$^{o}C$
C. 2000$^{o}C$
D. >2500$^{o}C$

Answer 1

The name oxy-acetylene itself indicates that it is a mixture containing both oxygen (Pure oxygen 99.5 %, not air) and acetylene. The oxy-acetylene flame was introduced in 1903 by a scientist Thomas Wilson.

Complete step-by-step answer: - In the question it is asked to find the temperature of the oxyacetylene flame.
- We know that acetylene is an unstable gas and which is easily flammable in nature.
- By combining proper proportions of oxygen and acetylene we can produce a temperature of nearly 3400 $^{o}C$ by burning them together with pure oxygen.
- Means we can produce the highest temperature (nearly 3000 $^{o}C$ ) by using oxy-acetylene flame.
- Therefore by using oxy-acetylene flame we can generate a temperature of >2500 $^{o}C$ .

Additional information:
- By using the temperature which is generated by burning of oxygen-acetylene we can cut the steel.
- In the steel industry, cutting the steel oxy-acetylene flame is more useful.
- Under the water to weld different metals oxy-acetylene flame is more useful.
- In silver soldering also oxy-acetylene flame is very useful.

So, the correct option is D.

Note: The process of burning acetylene with oxygen is called combustion. At the time of combustion of hydrocarbons with oxygen we will get a huge amount of carbon dioxide and huge amounts of heat are the products. By using the liberated heat we can cut or weld different metals.
