There are only 3 states of matter which are solid, liquid, gas, and plasma....
what is 5th one?
The fifth is probably antimatter, which would fit with the stupidity of the quiz maker.
Experiments have proven that Bone Einstein Condensate has many interesting characteristics. It can have a very high gradient in optical density. Its large fraction of particles occupy the same, namely the lowest energy state. Another important property is called coherence. Also, quantum mechanical tunneling. It means that a small fraction of the Condensate tunnels through this barrier.
A classical particle could not overcome that. The Josephson Effect always occurs when a weak link separates two macroscopic quantum objects. As atoms cool, they act more like waves and less like particles. Waves expand and overlap. Similar to steam condensing on a lid when it is boiled, water clumps together to form a drop of water. The same occurs with atoms; only it is their waves that merge.
Liquids have a fixed volume but no fixed shape because liquid particles are not so tightly constrained and have spaces in between them and are free to move compared to solids. Liquids do not have a fixed shape, but rather, they take the shape of the container in which it is placed.
The molecules are positioned in such a way that they can freely move around. Unlike a solid, liquids can continuously change shape. A liquid is nearly incompressible, meaning that it occupies nearly a constant volume over a wide range of pressure. A liquid displays the properties of a fluid.
Sublimation is the process of a solid going straight to a gas. As another answer stated, this can be seen with dry ice. When dry ice 'melts' it just creates a fog and turns back into the gaseous state of carbon dioxide. Sublimation is a change in the state of matter, just like melting, freezing, and evaporation.
It can be looked at as such: a solid that has a very low melting point, it won't melt, but it will immediately 'boil' and evaporate. The process would be similar if you had a super stove that could boil and evaporate water at a moment's notice.
Solids cannot change due to their atom structure. Unlike gas or a liquid, a solid contains atoms which are closely packed together. Therefore, solids can't change shapes. Solids have a fixed volume and shape and are usually unable to flow, except in the case of glaciers. The atoms inside a solid are not allowed to move around too much.
The molecules in a solid are stuck in a specific structure or arrangement of atoms. The atoms still vibrate, and the electrons fly around in their orbitals, but the entire atom will not change its position. Another feature of liquids is that they are difficult to compress. Compressibility is the ability of a substance to change shape by applying pressure. Fluids, because they flow, can occupy whatever shape their container has, so they do not possess a fixed shape.
A scanning tunneling microscope is an instrument for imaging surfaces at atomic level. It is an electron microscope that shows three dimensional images of a sample. It is based on the concept of quantum tunneling. It is based on tunneling, in which wave-like properties of electrons permit the tunnel past the surface of a solid into areas of space that are forbidden to them under the rule of traditional physics.
The expectation of finding such tunneling electrons decreases as the distance from the surface increases. The STM makes use of this extreme sensitivity to distance. For an STM, good resolution is .01nm lateral resolution and 0.01 nm depth resolution.
You can see certain gases, such as chlorine and fluorine, but only because they are colored. Most gases are colorless and cannot be viewed. Gas is a material that knows no bounds of its own. Because most gases are hard to observe directly, they are described through the use of four physical properties or characteristics.
These include pressure, volume, number of particles, and temperature. Gas particles are widely disengaged from each other, and they have weaker intermolecular bonds than liquids or solids. Also, there is a place between the absorption spectra of oxygen and water where not much light gets absorbed. We can't see atmospheric gases because they don't have a color in visible range.
Room temperature is the range of air temperatures that most people prefer for indoor settings. As a medical definition, the range generally considered suitable for human occupancy is between 15 degrees Celsius and 25 degrees Celsius. Human comfort tends to depend upon the level of humidity, air circulation, and other factors.
In specific fields, like science and engineering, and within a particular context, room temperature can mean many different agreed upon ranges. Many things are associated with room temperature. These include water, fruit and produce such as apples and bananas, and red wine is traditionally served at room temperature.
No definate shape and a definate volume this is the correct answer
