When you swim underwater, the pressure of the water pushes against your chest cavity and subsequently reduces the size of your lungs. for every 10 m below the water surface, the pressure exerted by the water adds 14.7 psi to atmospheric pressure so 10 m below the surface would have a total pressure of 29.4 psi. if a swimmer has a lung volume of 6 l at sea level (atmo- spheric pressure), what would the volume of he lungs be when she is at the bottom of a pool that is 5 m deep?

The volume of the lungs at 5m deep is 4L

Explanation:

Hello!

We can solve this problem considering that the air inside de lungs behave as an ideal gas, and that the temperature is the same at sea leavel and 10 m below the surface, in this case:

P1 V1 = P2 V2   -- (1)

wher P and V stands for pressure and volume, and 1 and 2 for the intial (sea level) and final (5m below) states.

We know that:

P1 = 14.7 psi

V1 = 6 L

And if the pressure exerted by the water adds 14.7 psi to atmospheric pressure so 10 m below the surface, then at 5 m below it must add 14.7/2 psi, therefore:

P2  = (14.7/2) psi + atmospheric pressure = 7.35 psi + 14.7 psi

P2 = 22.05 psi

Solving equation (1) for V2:

V2  = V1 (P1/P2) = 6 L (14.7 psi / 22.05 psi ) = 6 *(2/3) = 4 L

The volume of the lungs at 5m deep is 4L

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
