5. (10 Points) The volume of air in the lungs of a typical human is 6.0 L. Traditional free divers, known for their ability to hold their breath during long
dives while gathering objects from the ocean bottom, could descend
underwater to a depth of 30 m where the pressure is four times that at the
surface. What would be the volume of air in their lungs at 30 m?

the picture is work for number 1,2,4,5,7

Explanation: number 3: as the pressure in the volume decreases, the volume increases causing it to expand and eventually blow.

number 6: because the temperature and the amount of gas don’t change, these terms don’t appear in the equation. What Boyle’s law means is that the volume of a mass of gas is inversely proportional to its pressure. This linear relationship between pressure and volume means doubling the volume of a given mass of gas decreases its pressure by half.

hope this helps :))

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
