Property intensive

This ester, isopropyl methylphosphonofluoridate (X), is a colourless liquid. It is more toxic than D.F.P., but shows very similar physiological properties, intense myosis, respiratory collapse, powerful anticholinesterase activity, etc. The liquid passes rapidly through the skin. At the end of World War II, two plants were under construction in Germany for the production of the material on a large scale. [Pg.105]

Table I consists of a compilation of r /4> ratios as a function of X. Our results and those presented for p-GaP and n-ZnO are in rough agreement with this simple model (8,9,30,31,32). Construction of a more refined model awaits incorporation of other data (nonexponential lifetimes, electroabsorption, carrier properties, intensity effects, quantitative evaluation of 4>nr by photothermal spectroscopy, e.g.) and examination of other systems.

In the mid-19th century the Calabar bean was sent to Scotland and the two principal alkaloids were extracted in a number of European laboratories. There the formulae were determined and toxic and medicinal properties intensively studied. By the early 20th century the formula for physostigmine and the presence of two... [Pg.391]

The name tungsten bronzes originates from their characteristic properties intense color, metallic luster, metallic conductivity or semiconductivity, a range of variable composition, and resistance to attack by non-oxidizing acids. The bronzes Na W03 exhibit colors that change with the occupancy factor x as follows ... [Pg.391]

One of the striking features of interstellar maser emission is the enormous intensity the maser lines have. In the case of water, the brightness temperature for the source W49 reaches about 1015 °K. Furthermore, the line widths of the observed lines are extremely narrow, typically only a few ten of kHz. Both properties, intense and narrow emission lines, are intrinsic indications of maser emission. It has been found that the angular size of all interstellar maser sources is very small, i.e. much smaller than the spatial resolution obtained with large single dish radiotelescopes. From long baseline interferometry, however, an upper limit has been placed on the apparent source size of about 0.002 seconds of arc (for W49 = 0.0003 , Orion = 0.001 ) (Hills et al., 1972), which, for example, at the distance of Orion, 450 pc, makes this particular water vapor source about 1/2 AU in size. This is comparable with the diameter of a red... [Pg.54]

Some properties of a sample of a substance depend on the quantity of the sample. These properties are called extensive properties. For example, the weight of a solid sample depends on how much of the substance is present. Other properties, such as color and taste, do not depend on how much is present. These properties are known as intensive properties. Intensive properties are much more useful for identifying substances. [Pg.18]

Since 1,2,4-triazines can be considered as azapyrimidines, a great number of 6-azapyrimidine nucleotides and nucleosides have been prepared and their properties intensively studied, for instance... [Pg.508]

Fugacity is a thermodynamic property intensively used in chemical engineering, the most important being chemical equilibrium of gases at high pressures, and vapour-liquid equilibrium. The first subject is not covered here, but second topic will be discussed in detail in Chapter 6. Therefore, the problem is how to calculate fugacities... [Pg.156]

The balance equation cannot be applied to uncountable individuals (units) or to intensive properties. Intensive properties are independent of the amount of matter present. Some examples are temperature, pressure, viscosity, hardness, color, honesty, electric voltage, beauty, and density. An example of uncountable individuals is all the decimal fractions between 0 and 1. [Pg.79]

Some properties, such as temperature and melting point, are intensive properties. Intensive properties do not depend on the amount of sample being examined and are particularly useful in chemistry because many intensive properties can be used to identify substances. Extensive properties depend on the amount of sample, with two examples being mass and volume. Extensive properties relate to the amount of substance present. [Pg.11]

Some physical properties are extensive properties, properties that depend on the amount of matter present. Mass and volume are extensive properties. Intensive properties, however, don t depend on the amount of matter present. Color is an intensive property. A large chunk of gold, for example, is the same color as a small chunk of gold. The mass and volume of these two chunks are different (extensive properties), but the color is the same. Intensive properties are especially useful to chemists because they can use intensive properties to identify a substance. [Pg.24]

The thermodynamic properties of a system at equilibrium consists of two types of properties, intensive and extensive properties. The roost common intensive properties encountered are the temperature, T, and pressure, P, which are... [Pg.13]

A characteristic of a system is called a property. Intensive properties do not directly depend on the amount of matter in the system (for example temperature and pressure). Extensive properties, for example mass and volume, do directly depend on the number of particles. The ratio of two extensive properties becomes intensive in nature. [Pg.178]
