If I were ever to be involved in a serious car crash, I would trust airbags to improve my chances of having less severe injuries. They save numerous lives every year by spreading the force of the impact to a larger area, lessening the brunt of the collision
This law relates to airbags because at a constant pressure, the volume and temperature are constant. As the bag fills with hot air (T1), the volume of the bag also increases(V1), and when the reaction slows, decreasing the temperature (T2), the volume of the bag decreases (V2) which also lessens the impact.
Airbags have been around since the 1950’s, but Allen Breed was the first to patent it in 1968. Airbags are gas-inflated cushions in steering wheels and some side compartments that expand rapidly to protect people during car crashes. They work by a spark igniting Sodium Azide which releases Nitrogen gas into the bag to fill it, yet when the person actually hits the bag, it has already begun to deflate to provide more of a buffer.
