As one could surmise, airbags are sacks of gas, but complicated ones. an airbag is pre packaged and folded up in the steering wheel of the car, and when an accident is detected, a small explosive (sodium azide) is detonated, which produces large amounts of nitrogen gas. Given avagadro’s law on the relationship between moles of a gas and the volume of a gas, the bag inflates fully because of the direct relationship. the bag then immediately begins to deflate, in order to lessen the impact on the driver. Image

  1. I was thinking that the reaction caused an increase in temperature, which would increase volume, meaning that Charles’s law applies to the increase in volume. Why do you think that it is based off of a mole: volume relationship?
