Which of the 7 dwarves would come first alphabetically?
The seven dwarfs are fictional characters from Snow White and the Seven Dwarfs. The dwarf that would come first alphabetically is Bashful.
What are tiny woman called?
petite or, in a medical condition sense, dwarfs
How big is a neutron?
its difficult to talk about size, when talking about such particles. Maybe someone will correct me, but my understanding is that electrons and protons have no size: we say they are point particles. They have a probability wave which shows where they are likely to appear, but I don't think they actually have a volume as, in the same way, a swimming pool or a car would have. We can estimate the size of a nucleus, which consists of neutrons and protons, then divide that volume by the total number of nucleons, which would probably give a value of 10^-15m, but can you actually say that a free floating neutron has a volume? I don't know. Electrons certainly dont. We say they are point charges.
Can all matter be classified as solid liquid or gas?
No. While most matter on Earth is in one of those three states, not all of it is. A gas that ionized (electrons have broken free of atoms or molecules) enters a fourth state of matter called plasma. Plasma can be found in electrical arcs such as lightning and where substances are heated to extreme temperatures. The sun is plasma. At high temperatures and pressures some substances that are normally liquids or gasses can become supercritical fluids, a state that is intermediate between liquid and gas. At temperatures near absolute zero some materials can from a Bose-Einstein condensate, in which atoms stop acting as individual particles and start acting as a uniform wave. The cores of many dead stars form white dwarfs, which are are composed of electron-degenerate matter, a state thousands of times denser than anything found on Earth. The cores of massive stars may form neutron stars, which are composed of neutron-degenerate matter, which is millions of times denser than electron-degenerate matter.
The longest lived stars are expected to undergo fusion reactions for?
Billion and billions of years. It has been suggested that any red dwarfs created soon after the big bang are still in existence and will continue to be so for the same amount of time ~ 26 billion years plus.
How is degeneracy pressure related to white dwarfs and neutron stars?
White dwarfs are prevented from collapsing further by electron degeneracy pressure. If the mass of a stellar remnant exceeds the Chandrasekhar limit, about 1.4 solar masses, gravity will overcome this pressure and form a much smaller and denser neutron star. Further collapse in a neutron star is prevented by neutron degeneracy pressure up until the Tolman-Oppenheimer-Volkoff limit of about 3 solar masses, at which point gravity causes a complete collapse, forming a black hole.
Why do white dwarfs not continue to contract as they cool?
White dwarfs do not contract because the electron degeneracy pressure is stronger than gravity for stars with masses like white dwarfs. It holds them apart.
What do white dwarfs and neutron stars have in common?
Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.
What has the author Dongsu Kyu written?
Dongsu Kyu has written: 'Neutron stars and white dwarfs in galactic halos?' -- subject(s): White dwarfs, Neutron stars
What is the diffrance between stars that become white dwarfs and stars that become neutron stars?
Stars that become white dwarfs die but become black holes . Neutron stars are born from a Super Nova that stored its energy and became a neutron star.
What are the smallest stars?
The smallest stars are called neutron stars.They typically have a diameter of only 12kmthe smallest star is the neutron star from the word "neutron"
What stars have the highest densities?
Black holes, neutron stars, and the white dwarfs
What ordinarily keeps a star from collapsing?
Further collapse is prevented by electron degeneracy pressure.
What is a Very small hot star?
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
What is a small hot very dense star?
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
Explain why the sun does not collapse under the force of its own gravity?
Stars do not collapse because the inward force of gravity is balanced by the pressure generated by fusion. When stars die they do collapse. The cores of low to medium mass stars collapse to form white dwarfs. Further collapse is prevented y electron degeneracy pressure. More massive stars leave behind neutron stars, in which gravity is balanced by neutron degeneracy pressure. In the most massive stars, once fusion stops producing energy there is nothing to stop the collapse and the core becomes a black hole.
What is degenerate matter?
Degenerate matter is extremely dense matter with characteristics governed by quantum mechanics. One of the notable traits is that temperature and pressure are independent of one another. Two forms of matter known to exist are electron degenerate matter, which comprises white dwarfs, and neutron degenerate matter, which comprises neutron stars.
