State of matter Definition and 31 Threads

Recent Science headlines are abuzz about a new theory. Physicists claim information is the fifth state of matter. By 2245, half of Earth’s mass could be converted to digital bits https://www.zmescience.com/science/news-science/information-fifth-state-matter-0252/ Digital Information Threatens...

We all know that the state of matter can be changed by increasing temperature or by applying pressure. And, all of these, in some way lead to a change in the particles' speed. The speed of the particle decides the state of matter. So, if we were to throw an object at very high speeds, like 50%...

Hi, In electro-chemical cells (galvanic, concentration, etc) or more generally when some RedOx reactions occur in solutes, is there always a phase change? I mean is there always a change in the state of matter from liquid to solid or gas?

Hi. In all of my question, I mean degrees celsius when I say degree. Think we have a 0 degree ice. we give some energy to it (by a heater) and all of it get into a 0 degree water. How does the kinetic and potential energy of the molecules change? In the book in which I saw this question, it...

I came across this beautiful pearl https://arxiv.org/abs/1710.02105 https://arxiv.org/pdf/1710.02105.pdf which I like to bring to notice. Despite of its title it is heavier on theoretical physics than it is on mathematics, so I placed it in this forum. I think it is equally interesting to those...

I know that Quark-gluon plasma is the hotter state of matter that we know. Soo is solid the coldest state of matter ? If there is no so sorry for my stupid brain!

Aside from solids, are any of the known states of matter (exotic or otherwise) considered to not be fluids? As a side note, I'd like to appologize in advance if this turns out to be posted under the wrong category of physics, I could not tell which category this would fall under and this seemed...

What is an (the?) empirically demonstrable method used for determining a substance's state of matter? If a new substance was discovered and scientist A said it's solid and scientist B said it's a liquid, how would it be demonstrably proven to be one or the other? The books I have define states...

In another forum someone states that "cacao powder" cannot be considered as a "solid state" since "it cannot sustain shear stresses". Has this statement any basis? -- lightarrow

Does anybody know where I could find worksheet to practice naming the state of matter in chemical reactions (with answers in the worksheet to check) as I have problems with that. Especially deciding when it is aqueous. I know (well at least i am right) that when you have acid as reactants it has...

Homework Statement Imagine a hypothetical process in which the methane molecule, CH4, is "expanded," by simultaneously extending all four C−H bonds to infinity. We then have the process: CH4 (g) → C(g) + 4H(g) Compare the reaction for the "expansion" of methane with the reverse of the reaction...

Starting from a gas state and reaching the liquid state by getting around the critical point in a p-T phase diagram, what happens (qualitatively) to the molecules (or atoms)? Does a fraction of them start to form bonds? This concept of "indistinguishable" liquid and gas is new to me.

What state of matter are atomic particles be in? A friend of mine suggested they might be virtual particles.

The graph should look something like this http://en.wikipedia.org/wiki/File:12-6-Lennard-Jones-Potential.svg (the other information has nothing to do with what I ask though, only the shape of the graph for clarity sake) My question is, does resultant force = 0, or when potential energy is...

Hi, I'm studying Roman culture and civilizations in a course at my university and I'm learning how poets and philosophers argued that the natural state of matter is in motion, that everything is always in motion and never at rest, that there is an empty void that exists between objects and...

Hi, I'm new to particle physics, and recently became a little bit interested in antimatter. einstein said that energy is just matter in a different form. I came to that conclusion on my own even before reading about E=mc squared, and I wonder: could energy be considered a state of matter? I...

We've all heard of the three states of matter: solids, liquids, and gases. Recently someone told me that there is some sort of state of matter between a liquid and a gas. Does anyone know what he's talking about?

Hi, Judging by the questions and answers, there are obviously many talented physics and astrophysics professionals here. I am not one of these professionals, nevertheless I am interested in this field. So please excuse my naïve questions and thanks for any help answering them. I have been...

is there a state of matter called the supercool state or something..if yes,can someone please elaborate?..if no,can someone please reply about the states of matter..?

Is Light a State of Matter? This is a question many people have asked for a long time. What is your opinion on this topic? I believe that light IS a state of matter contrary to popular belief. Because all energy needs something to carry it through. I think light is an extremely high energy...

Homework Statement Hi all I have conceptual problems : 1. In cold countries, water in pipe lines freezes in winter season. Freezing causes volumetric expansion and may burst the pipes. My question :why freezing causes volumetric expansion? 2. Mostly, substance increases their...

How do pressure, density, state of matter, and temperature relate? these are my points, are they right?: 1. Higher temperature makes an object less dense 2. Density governs the state of matter for the object, hence as water becomes less and less dense, it becomes gas (water vapour) 3...

While having a discussion with a friend the idea of fire being the fourth state of matter came up, in other words, a hot enough fire or "flame" can be considered plasma being the fourth state of matter. My response to this was, "No, fire or a "flame" is always in the gas phase, fire is the rapid...

A team of scientists from Princeton University has found that one of the most intriguing phenomena in condensed-matter physics -- known as the quantum Hall effect -- can occur in nature in a way that no one has ever before seen. Writing in the April 24 issue of Nature, the scientists report...

If every thing is either 'solid', 'liquid' or 'gas' then what is fire? wirefree

just wondering how can matter be at a state for absolute 0 (0 kelvin), because it would mean that electrons arent moving , and that they've got no energy. Nothing moving doesn't seem very possible because there's the 4 fundamental forces ( example : how can the gravitational force of an...

Recently, I have been studying for a chemistry placement exam for college. On the sample exam (which I have been studying with), one of the questions asks, "Which of the following substances is a gas at 20 degrees Celsius and one atmosphere of pressure? A.) O3 B.) C C.) I2 D.) Ca...

How do you know if something is a solid, liquid or gas. Like ferrous iodide or sodium phosphate?

what is the 5th state of matter can aybody explain it

hey guys i need a little help here my introduction to chemistry teacher wants us to find the 7th state of matter for extra credit. I've searched and i can't find it, but if you could provide a little insight or an article that would be wonderful. we know about the bose-einstien and neutron...

I just finshed "Einstein's Cosmos" my Michal Kaku, in this book Dr. Kaku takes about the 5th state of matter or Einstien-Bosen Condinstate, which the book says occurs at extermly low temperatures. I never knew that matter exisited in this form (is it true that einstein-bosen condistate...
