Suppose you have avogadro\'s number of mini marshmallows and use them to cover the state of california which has a land area of 1.560 × 105 mi2. each mini marshmallow has a diameter of 0.635 cm and a height of 2.54 cm. assuming the marshmallows are packed together so there is no space between them, to what height above the surface, in kilometers, will the mini marshmallows extend

The height that avogadro's number of mini marshmallows covering the land area of California will extend is 1199.6 km above the surface.

The Avogadro number is a constant which gives the number of elementary particles present in 1 mole of a substance.

The value of the Avogadro number is 6.02 × 10^23

Avogadro number of mini marshmallows = 6.02 ×10^23 mini marshmallows.

Assuming each marshmallow is a small cylinder, then the area of its circular base is:

Area circular base = π*r²

Area circular base = π * (0.635/2)²

Area circular base = 0.317 cm²

6.02 × 10^23 marshmallows will cover an area of 6.02 × 10^23 * 0.317 cm² 

Area covered = 1.908 × 10^23 cm² = 1.908 × 10^13 km²

The land area of california is  1.560 × 10^5 mi² = 4.04 × 10^5 km²

The number of times the 6.02 × 10^23 marshmallows will cover the land area of California is obtained by division:

Number of times = 1.908 × 10^13 km² / 4.04 × 10^5 km² =  4.7227 ×10^7 times

To obtain the height of the mini marshmallows, the height of a mini marshmallow is multiplied by the number of times the mini marshmallows will cover the land area of California.

Height = 4.7227 × 10^6 * 2.54 cm

Height = 1.1996 ×10^6 cm

Height in kilometres = 1199.6 km above the surface

Therefore, the height of avogadro's number of mini marshmallows covering the land area of California is 1199.6 km above the surface.

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!
