What would be a real-life example of the ideal gas law?

AI Thread Summary
A real-life example of the ideal gas law is the operation of an airbag in vehicles, which inflates using nitrogen gas produced from a reaction involving sodium azide. This reaction generates nitrogen gas and sodium metal, while a secondary reaction with potassium nitrate neutralizes the sodium to prevent overinflation. The ideal gas law, represented by the equation PV = nRT, governs the relationship between pressure, volume, and temperature during this process. The airbag effectively protects passengers' heads during a car crash by ensuring it inflates properly. Understanding these chemical reactions highlights the practical application of the ideal gas law in everyday safety devices.

What is a real-life example of the ideal gas law?

Homework Equations


PV = nRT
(Pressure x volume = number of moles x the gas constant x temperature in Kelvin)

Mechanics of an airbag. As airbag expands, they fill with the right kinds of gases and inflates properly and are filled with nitrogen gas. The nitrogen gas is produced by a reaction with sodium azide, this reaction causes nitrogen gas and sodium metal. While nitrogen is filling the airbag, sodium metal is reacting with potassium nitrate, and this reaction neutralizes the sodium. This helps because it makes enough gas so the airbag doesn't overfill, but does inflate (enough). As we know, the airbag protects the passenger's head in the event of a car crash.

Hello @Lolaamaigatti04 !
:welcome:
(By the way: There's no subscript needed for the n in the ideal gas Law equation: PV = nRT .)

You appear to have quoted an excerpt from a Web site called "Reference". That's kind of a strange name for this site considering I could not find any references for the sources of the few articles I looked at there. No author listed for the one you quote nor from one other I looked at. Here's an image from the first part of the article - a part you didn't quote from.

Thanks for the tip! (about the subscript) Yes, that is a strange name. Also, I didn't directly quote the passage. :sorry:
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
