Answer :
Final answer:
A pressure gauge is necessary when using nitrogen cylinders to measure and monitor the pressure, controlling the amount of gas being released and avoiding accidents due to overpressure.
Explanation:
Since nitrogen cylinders can be charged to such high internal pressure, a pressure gauge is necessary when using the nitrogen. Gauges are used to measure and monitor the pressure in gas cylinders or any other enclosed system, like nitrogen cylinders. They are useful to control the amount of gas being released and prevent accidents due to overpressure. Compressed gases such as nitrogen are used in many industrial as well as medical applications. For example, large volumes of atmospheric nitrogen are necessary for making ammonia, a key starting material in numerous chemical industries. Additionally, nitrogen gas is used in airbags, where a rapid chemical reaction generates gaseous nitrogen to deploy and inflate the airbag in a fraction of a second.
