If a gap exists between the solidus and liquidus it is called the freezing range, and within that gap, the substance consists of a mixture of solid and liquid phases (like a slurry). Such is the case, for example, with the olivine ( forsterite - fayalite ) system, which is common in Earth's mantle .
These properties are explained by the theory that the common isotope helium-4 forms a Bose–Einstein condensate (see next section) in the superfluid state. More recently, fermionic condensate superfluids have been formed at even lower temperatures by the rare isotope helium-3 and by lithium-6 .
Phase transitions commonly refer to when a substance transforms between one of the four states of matter to another. At the phase transition point for a substance, for instance the boiling point, the two phases involved - liquid and vapor, have identical free energies and therefore are equally likely to exist.
Visual thinking, also called visual or spatial learning or picture thinking, is the phenomenon of thinking through visual processing. [1] Visual thinking has been described as seeing words as a series of pictures. [2] [3] It is common in approximately 60–65% of the general population. [1] "Real picture thinkers", those who use visual thinking ...
Since Cu-Ag is a true eutectic, any silver with fineness anywhere between 80 and 912 will reach solidus line, and therefore melt at least partly, at exactly 780 °C. The eutectic alloy with fineness exactly 719 will reach liquidus line, and therefore melt entirely, at that exact temperature without any further rise of temperature till all of ...
Sometimes a picture speaks a thousand words. In this case, a simple animated illustration, the thesis project of Jonathan Jarvis, a student at the prestigious Art Center in Pasadena, CA, manages ...
The following outline is provided as an overview of and topical guide to thought (thinking): Thought is the object of a mental process called thinking, in which beings form psychological associations and models of the world. Thinking is manipulating information, as when we form concepts, engage in problem solving, reason and make decisions ...
At least 217 people are dead after Spain was struck by the worst floods in recent memory that submerged towns, toppled bridges and cut entire communities off from the outside world.
