Two examples of Bose-Einstein condensates include superfluids, such as cold liquid helium, or superconductors, such as the nucleons inside a neutron star. Bose-Einstein condensates are another state of matter, similar to solids but with less energy. They were not directly observed until the 1990s, even though Einstein predicted their existence in the 1920s.Know More
Bose-Einstein condensates exhibit peculiar characteristics and form in only the most extreme circumstances. In the case of a neutron star, the atoms are crammed so closely together that they behave as though they were a single atom. Neutron stars are among the densest objects known in the universe. If a baseball were made of the material from a neutron star, it would weigh more than 20 trillion kilograms. In fact, the escape velocity required to launch a rocket from the surface of a neutron star is about half of the speed of light.
Cold liquid helium becomes a superfluid. This means that the substance has no viscosity, or resistance to flow. A glass container full of supercooled helium cannot contain the substance. This is because the individual helium atoms can squeeze between the atoms of glass. Additionally, when kept in a container, such superfluids will crawl up the sides of the vessel and spill over the edge.Learn more about States of Matter
Examples of gases include oxygen, nitrogen, helium, hydrogen, argon, fluorine, krypton, neon, radon, xenon and chlorine. These gases are single elements, though many gases are compounds or mixtures. Such gases include carbon dioxide, carbon monoxide, methane, air, ammonia, formaldehyde, ozone, nitrous oxide and natural gas.Full Answer >
Water, ethanol, household bleach, blood, paint, milk, gasoline, mineral oil, acetone and butyl alcohol are examples of liquids. Liquids' properties allow them to flow or be poured easily into containers.Full Answer >
Melting point, boiling point and thermal conductivity are examples of characteristic properties. Characteristic properties of matter are inherent properties that are unique and identifying under specific conditions.Full Answer >
Amorphous solids include glass, plastic, gels and thin films. An amorphous solid is one of two types of solid, the other type being crystalline. An amorphous solid has no repeated pattern of orientations and positions of its constituent atoms and the bonds between them.Full Answer >
