If you like m-theory (I do) it would be the string.

It depends what you mean by small and volume.\n\nIf by small you mean mass, then for a black hole to form spontaneously by gravitational collapse it requires a minimum of around 6 solar masses (6 times the mass of our sun). In principle you could forcibly compress matter to form a smaller black hole, but in practice it is not clear how - or whether - you could do this.\n\nVolume is more complex. If you mean the volume contained by the Schwarzchild radius (or event horizon) then this can be very large indeed - many times the volume of our solar system for the black hole belived to be at the centre of the galaxy. \n\nIf you mean the volume of the collapsed matter, then this is zero, because a black hole is a singularity.

liquid? if u mean state of matter.

i think...\nthe atom is the smallest thing u will ever find, it doesnt divide into anything. so when you cut it up, or split it, it kind of explodes. so an atom bomb is alot of atoms exploding at the same time. funny how the smallest things in the world cause the biggest damage possible, huh?

Matter and Anti-Matter

Relatively new states of matter. After these discoveries the total states of matter are now 6. Einstein predicted these so they are named after him. BECs(bose-einstein condensates) are new form of matter at the coldest temperatures in the universe. A Bose-Einstein condensate is a phase of matter formed by bosons cooled to temperatures very near to absolute zero. \n\nThe fermionic condensate is a superfluid phase formed by fermionic atoms at low temperatures. It is closely related to the Bose-Einstein condensate, a superfluid phase formed by bosonic atoms under similar conditions. Unlike the Bose-Einstein condensates, fermionic condensates are formed using fermions instead of bosons.

The definations wanted by you are given below-\n\nIn physics, matter is commonly defined as the substance of which physical objects are composed, not counting the contribution of various energy or force-fields, which are not usually considered to be matter per se (though they may contribute to the mass of objects). Matter constitutes much of the observable universe, although again, light is not ordinarily considered matter. Unfortunately, for scientific purposes, "matter" is somewhat loosely defined.\n\nMass is a property of a physical object that quantifies the amount of matter and energy it is equivalent to. Mass is a central concept of classical mechanics and related subjects, and there are several forms of mass within the framework of relativistic kinematics (see mass in special relativity and mass in General Relativity). In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.\n\nAn elementary particle is a particle with no measurable internal structure, that is, it is not a composite of other particles. They are the fundamental objects of quantum field theory. Elementary particles can be classified according to their spin, with fermions having half-integer spin and bosons integer spin.\n\nSpace has been an interest for philosophers and scientists for much of human history. The term is used somewhat differently in different fields of study, hence it is difficult to provide an uncontroversial and clear definition outside of specific defined contexts. Disagreement also exists on whether space itself can be measured or is part of the measuring system. (See Space in philosophy.) Many fields use an operational definition in which the units of measurement are defined, but not space itself.\n\nIn chemistry and physics, an atom (Greek  átomos meaning "indivisible") is the smallest particle of a chemical element that retains its chemical properties. \n\nA chemical element, often called simply an element, is a substance that cannot be decomposed or transformed into other chemical substances by ordinary chemical processes. All matter consists of these elements and as of 2006, 117 unique elements have been discovered or artificially created. The smallest particle of such an element is an atom, which consists of electrons centered about a nucleus of protons and neutrons.\n\nIn chemistry, a molecule is an aggregate of two or more atoms in a definite arrangement held together by chemical bonds. Chemical substances are not infinitely divisible into smaller fractions of the same substance: a molecule is generally considered the smallest particle of a pure substance that still retains its composition and chemical properties. Certain pure substances (e.g., metals, molten salts, crystals, etc.) are best understood as being composed of networks or aggregates of atoms or ions instead of molecular units.\n\nIn particle physics, antimatter extends the concept of the antiparticle to matter, wherein if a particle and its antiparticle come into contact with each other, the two annihilate —that is, they may both be converted into other particles with equal energy in accordance with Einstein's equation E = mc2. This gives rise to high-energy photons (gamma rays) or other particle–antiparticle pairs-.

Well, if you get something with the second to lowest potential energy in the world, that energy can go to the lowest potential energy thing in the world and that's it.  Otherthan that, no.  And there's nothing inherent in the material, unless you're talking about chemical reactions, in which case, I just don't know what those two things are.  I hope that's clear.

an atom- it is the smallest possible particle of an element that retains the properties of that element.\n\nan atom, being the smallest particle of an element is still composed of smaller particles: \n          • protons - particles with a weight or mass of 1 \n            amu (atomic mass unit) and has 1 positive \n            charge \n          • neutrons - particles with 1 amu and no charge \n            (neutral) \n          • electrons - particles with almost no mass \n            (almost 0 amu) and has 1 negative charge

At first, scientists thought the atom was the smallest possible particle. Then they thought the electron, proton and neutron were the smallest. Now we have the quarks and other basic particles.\n\nAlthough they haven't discovered if quarks are made up of even smaller particles, I will guess that in a few years, scientists will discover that they are made of something smaller yet.

We dont know, but to the best of our knowledge, matter is composed of atoms composed of protons, neutrons, and electrons.  Protons and neutrons are composed of hadrons which are composed of quarks (electrons are quarks).\n\nQuarks may be composed of strings, which are 1 dimensional particles, but we cant really say.  Thats our best theory.\n\nSome people believe strings are the absolute smallest things out there.  In fact, at the 'size' of strings, distance and size dosent really make sense, so if they exist they are proably as small as anything else.  That is not to say that they are not composed of more fundamental things, whatever they might be.  It is to say that size dosent make much sense beyond strings, so they can be called the smallest.\n\nEnjoy.

Matter can exist in either a liquid, solid, or gaseous state.  \nA) Iron nail is a solid\nB) Gasoline is a liquid unless you are speaking of the fumes that can be seen or smelled and then it is a gaseous state.

because of the surface tension forces between the liquid molecules the drop tries to get the smallest surface for the same amount of liquid and the sphere has the smallest surface for the same amount of material

Disregard butchtroll, he doesn't know anything and is obviously just guessing.\n\nA absolute zero, although practically impossible to reach, it is theoretically very easy to calculate. Just assume that all particles have a velocity of zero, and calculate the lowest potential structure according to the lennard-jones potential and possible electro-static potential. The result concludes a structure quite similar to crystals at living-room temperature.\n\nButch - practically as in cannot be obtained through anything but theoretical experiments. Although, temperatures can actually be achieved that is sufficiently low to allow, in some degree, to regard matter as having a temperature of absolute zero. Theoretically, if such matter should exist, it would affect the universe in any significant way. That the universe cease to exist if absolute zero was reached, would be a prerequisite, not a result. You can do that math yourself and see if it is possible - or borrow the particle similator program I've written.\n\nmore: I find it funny that you preach about humility, after calling me an idiot. Especially after mixing different types of energy together and calling the lot for temperature. Sure, if an atom contain absolutely no energy, it would collapse into a black hole. But temperature is NOT a measure of total energy.\n\nyet more: Still you call me an idiot, and still you attempt to call humiliary high ground. I'm not saying I know everything myself - but wheter temperature is all energy, or just momentum of "particles", is pretty far from'everything'. As a student in nanotechnology, I can honestly say that, you sir, are blinded by your own feeble knowledge of physics. Temperature of matter is usually described as the summation of vibrational, momentum, rotational energy and phonons. NOT electronic excitation or any kind of potential energy.\n\nYour question was inane, and I *did* answer it. Nothing would happen with the universe if a cloud of hydrogen would suddenly come into existence with a temperature of zero kelvin. If you don't understand what I'm writing, just say so, instead of stating that I didn't answer your question.\n\nWhat do you attempt to prove with your citation? You seem lost, sir?\n\nWhat do you need a value of? What the temperature of the solid hydrogen would be after 1 second? Sorry, but I don't care enough to calculate how much a certain amount of hydrogen crystal would increase in temperature from background radiation.

Two or more elements combined make a compound. The smallest amount of an element is an atom. The smallest amount of a compound is a molecule. "Chemical" is a term with a wide range of interpretations. Depending on context, a chemical can be an element, a compound, a man-made substance, etc. See ref.

All the fundamental particles are thought of as having no size.  They are all point particles as far as we know.  In reality they probably are all made up of something else...but we haven't been able to probe deep enough to know what that would be.\n\nSo, they are are smallest: quarks, leptons (electrons, neutrinos), and bosons (photon, gluons, W/Z, graviton), and more?
