When ice is left outside on a hot day, it melts, and then evaporates. which best describes what happens to the molecules in the ice?

Hello. You forgot to show the answer options. The options are:

"A.The molecules have a higher average kinetic energy after each of the phase changes.  B.The molecules move faster after the first phase change, but then start to move more slowly.  C.The molecules lose energy in the first phase change, but gain it back in the second phase change.  D.The molecules convert their kinetic energy into heat energy to cause the phase change"

D.The molecules convert their kinetic energy into heat energy to cause the phase change

Explanation:

The ice melts through the heat. When heat is provided, the atoms and molecules of the ice tend to vibrate with greater intensity (kinetic energy), increasing the temperature (thermal energy), which is a measure of the average kinetic energy of the particles. In this case, the temperature remains constant, but the arrangement of the atoms and molecules of the ice is modified.

With that, we can say that the ice melts and evaporates because the molecules convert their kinetic energy into thermal energy to cause the phase change.

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!

i wanna say it’s between b and d, leaning more towards b.
