In the question given below, there are two statements marked as Assert...
Assertion (A) : Leakages in household gas cylinders can be detected.
Reason (R) : LPG has a strong smell.
The correct option for this question is option 'C', which states that Assertion (A) is true but Reason (R) is false.
Explanation:
Assertion (A) : Leakages in household gas cylinders can be detected.
This statement is true. Leakages in household gas cylinders can indeed be detected through various means. Gas cylinders are designed with safety features to detect and prevent leakages. Some common methods to detect gas leaks include:
1. Smell: LPG (liquefied petroleum gas), which is commonly used in household gas cylinders, has a strong smell added to it. This is done intentionally to help people detect gas leaks easily. If there is a gas leakage, the strong smell of LPG becomes noticeable, alerting people to the danger.
2. Sound: Gas leaks can also be detected by listening for a hissing sound. If there is a leakage, gas escapes from the cylinder, creating a distinct sound that can be heard.
3. Soap Water Test: Another method to detect gas leaks is by using the soap water test. This involves applying a soapy solution to the gas cylinder valve and checking for the formation of bubbles. If bubbles form, it indicates a gas leak.
4. Gas Detectors: Gas detectors are devices specifically designed to detect the presence of gas leaks. These detectors use sensors to detect the gas concentration in the air and trigger an alarm if it exceeds a certain threshold.
Therefore, it is clear that leakages in household gas cylinders can be detected through various means.
Reason (R) : LPG has a strong smell.
This statement is false. LPG does not have a strong smell naturally. In its pure form, LPG is odorless and colorless. However, to ensure safety, a strong odorant called ethanethiol is added to LPG. This odorant gives LPG its characteristic smell, making it easier to detect gas leaks. Without the added odorant, it would be difficult to detect gas leaks as LPG is otherwise odorless.
Hence, the reason given is incorrect as LPG does not naturally have a strong smell.
In the question given below, there are two statements marked as Assert...
Leakages in household gas cylinders can be detected because of the strong smell of ethyl merceptan mixed with LPG.
