- 1. What is the functional purpose of an airbag? The functional purpose of an airbag is to give a cushioned surface for the driver of a vehicle during the time of the collision. On page one, paragraph three, states, “They are designed to supplement seatbelt restraints and help to distribute the load exerted on a human body during an accident.” The airbag helps to absorb and distribute the force of the impact caused by the result of collision. Since the airbag is filled with a gas (N2) it can slow down the forward motion which can prevent someone from creating a sudden collision in the steering wheel with a greater force. It may also prevent the person inside from being thrown from the vehicle during a crash. Thus, the functional purpose of an airbag is to protect the driver from collision with the steering wheel by minimizing the force of impact. 2. While a series of events take place within the airbag system, what ultimately causes the airbag, stored in the steering column,…1. What is the functional purpose of an airbag?

- In an experiment, sulfuric acid reacted with different volumes of sodium thiosulfate in water. A yellow precipitate was formed during the reaction. A cross drawn at the base of each flask became gradually invisible due the formation of this yellow precipitate. The time taken for the cross to become invisible was recorded. A partial record of the experiment is shown.
