There is an industrial coating process, known as evaporative deposition, whereby a solid material is heated to the gaseous state in a low-pressure chamber, the gas molecules travel across the chamber space and then deposit to the solid state on a target surface, forming a smooth and thin layer on the target surface. Again, the molecules do not ...
The air expands, reducing its density and rising. The rising air carries all the solid and liquid material from the eruption entrained in it upwards. As the column rises into less dense surrounding air, it will eventually reach an altitude where the hot, rising air is of the same density as the surrounding cold air.
A small piece of rapidly melting solid argon shows two concurrent phase changes. The transition from solid to liquid, and gas to liquid (shown by the white condensed water vapour). Other phase changes include: Transition to a mesophase between solid and liquid, such as one of the "liquid crystal" phases.
Taylor columns were first observed by William Thomson, Lord Kelvin, in 1868. [1] [2] Taylor columns were featured in lecture demonstrations by Kelvin in 1881 [3] and by John Perry in 1890. [4] The phenomenon is explained via the Taylor–Proudman theorem, and it has been investigated by Taylor, [5] Grace, [6] Stewartson, [7] and Maxworthy [8 ...
Gas: A compressible fluid. Not only will a gas take the shape of its container but it will also expand to fill the container. Mesomorphic states: States of matter intermediate between solid and liquid. Plastic crystal: A molecular solid with long-range positional order but with constituent molecules retaining rotational freedom.
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
It forms when rising heat and turbulent winds create spinning air currents, which can intensify into a tornado-like vortex. This vortex may pull in debris and gases, adding to the intensity of the ...
Iron-carbon phase diagram, showing the conditions necessary to form different phases. Distinct phases may be described as different states of matter such as gas, liquid, solid, plasma or Bose–Einstein condensate. Useful mesophases between solid and liquid form other states of matter. Distinct phases may also exist within a given state of matter.
