When it is a liquid, it can run 2 your fingers. When it is a gas, you may not 3 or feel it. Water can change from a solid to liquid or to a gas 4 . This is why we always have fresh water. Now let us find out 5 it changes. The heat of the sun turns liquid water into...
Gas chromatography, in analytical chemistry, technique for separating chemical substances in which the sample is carried by a moving gas stream through a tube packed with a finely divided solid that may be coated with a film of a liquid. Because of its s

gas, one of the three fundamental states of matter, with distinctly different properties from theliquidandsolidstates. The remarkable feature of gases is that they appear to have no structure at all. They have neither a definite size nor shape, whereas ordinary solids have both a definite size...

A heterogeneous reaction model is developed to represent the gas–solid reaction consisting of two-step reactions: formation of a solid intermediate on the core of unreacted solid and consumption of the solid intermediate. The presented model takes into account the shrinkage of both the unreacted cor...
Solid–liquid–gas reactions are ubiquitous and are encountered in both nature and industrial processes1–4. A comprehensive description of gas transport in liquid and following reactions at the solid–liquid–gas interface, which is substantial in regar
Gas giants,[2] also known as gas planets,[3] were large and massive planets composed chiefly of various gases.[2] They had no solid, well-defined surface,[4] which rendered them uninhabitable in themselves,[5] but at least some of them had a large number
