Assertion (A): If neutral flame is used in oxy-acetylene welding, both oxygen and acetylene cylinders of same capacity will be emptied at the same time.

Reason (R): Neutral flame uses equal amounts of oxygen and acetylene.

The correct answer is option 'A', i.e., both A and R are true and R is the correct explanation of A.

Explanation:

Oxy-acetylene welding is a commonly used welding process that utilizes a fuel gas, such as acetylene, and oxygen to generate a flame with high temperatures for welding applications. In this process, the fuel gas and oxygen are supplied from separate cylinders.

The neutral flame is one of the types of flames used in oxy-acetylene welding. It is achieved when the ratio of oxygen to acetylene is balanced, resulting in a flame with an equal amount of oxidizing and reducing properties. The neutral flame is characterized by a well-defined inner cone surrounded by a faint outer flame.

Neutral Flame:
The neutral flame is achieved by adjusting the oxygen and acetylene flow rates to obtain a stoichiometric ratio of 1:1. This means that for every molecule of acetylene, one molecule of oxygen is required for complete combustion. When the neutral flame is used, the amount of oxygen and acetylene consumed will be equal.

Reasoning:
The reason provided in the statement is correct. When a neutral flame is used in oxy-acetylene welding, equal amounts of oxygen and acetylene are required for combustion. As a result, both the oxygen and acetylene cylinders will be emptied at the same time if they have the same capacity.

Conclusion:
In conclusion, if a neutral flame is used in oxy-acetylene welding, both the oxygen and acetylene cylinders of the same capacity will be emptied at the same time. This is because the neutral flame requires equal amounts of oxygen and acetylene for combustion.
