Explanation:
Air bags help lessen injuries in an automobile crash is application of Boyle's law:
Boyle's law states that at constant temperature, the volume of given mass of a gas is directly proportional to the pressure changes.
According to this law, the volume of the air bag will increase. The bag will become bigger as a result of decrease in the gas pressure in the bag.
The bag was packed with gases under high pressure and their volume decreases appreciably. After a collision, pressure reduces and the gas expands.
helium balloon decreases in size when you put it into a freezer
A can of spray paint will explode if tossed into a fire
Both are application of Charles's law:
According to this law "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".
The helium balloon decreases in size because the temperature is lowered. The particles will keep tending towards a state of rest.
A can spray paint explodes because the gas in it will keep expanding as the temperature increases in a fire.
