Charles law

Charles law, also known as Gay-Lussac s law, states that the volume of a given mass of gas varies directly as the absolute temperature if the pressure remains constant, that is.  [c.528]

Tlie two precursors of tlie ideal gas law were Boyle s low and Charles law. Boyle found tliat tlie volume of a given mass of gas is inversely proportional to die absolute pressure if die temperature is kept constant, tliat is,  [c.126]

From combined Boyle s and Charles Law Equation of State for Perfect Gas  [c.409]

Ideal (or perfect) gas behavior is approached by most vapors and gases in the limit of low pressures and elevated temperatures. Two special forms of restricted utility known as the Boyle s law and the Charles law preceded the development of the perfect gas law.  [c.337]

Charles Law. At constant pressure (P), the volume (V) of a given mass of an ideal gas is directly proportional to the absolute temperature (T)  [c.337]

Pressure, temperature, and volume are properties of gases that are completely interrelated. Boyle s law and Charles law may be combined into one equation that is referred to as the ideal gas law. This equation is always true for ideal gases and is true for real gases under certain conditions.  [c.557]

As oil is pumped into the accumulator, compressing the nitrogen, the nitrogen temperature increases (Charles law). Therefore, the amount of oil stored will not be quite as much as calculated with Boyle s law unless sufficient time is allowed for the accumulator to cool to atmospheric temperature. Likewise, when oil is discharged, the expanding nitrogen is cooled. So, the discharge volume  [c.606]

If a fixed quantity of gas is held at a constant pressure and heated or cooled, its volume will change. According to Charles law, the volume of a gas at constant pressure is directly proportional to the absolute temperature. This is shown by the following equation  [c.633]

Pressure, temperature, and volume are properties of gases that are completely interrelated. Boyle s law and Charles law may be combined into the following ideal gas law, which is true for any gas  [c.633]

Basic concepts discussed here are atmospheric pressure vacuum gage pressure absolute pressure Boyle s law or pressure/volume relationship Charles law or temper-ature/volume relationship combined effects of pressure, temperature and volume and generation of pressure or compression.  [c.635]

Charles Law states that, for an ideal gas, the volume at constant pressure is proportional to the absolute temperature  [c.4]

Charles s law At constant pressure the volume of a given mass of gas is directly proportional to the absolute temperature.  [c.89]

Charles s law, which is a quite difTerent law, is also sometimes referred to as Gay-Lussac s law.  [c.188]

Olin Raschig Process. One process used by the Olin Corp. in its Lake Charles, Louisiana, facihty is an adaptation of the basic Raschig process (Fig. 4). Liquid chlorine is continuously absorbed in dilute sodium hydroxide to form sodium hypochlorite, cooled by an external brine recirculating loop to prevent hypochlorite decomposition and chlorate formation. The chlorination is automatically monitored by measuring the oxidation potential of the recirculating stream. Excess sodium hydroxide in the sodium hypochlorite is kept low (less than 1 g/L) to avoid caking in the salt crystallizer and to improve yields somewhat (97). The sodium hypochlorite is mixed with about a threefold molar excess of aqueous ammonia in the chloramine reactor chloramine formation is almost instantaneous at about 5°C. To this chloramine-containing stream is added immediately a 20—30 molar excess of anhydrous ammonia under sufficient pressure to keep ammonia in the Hquid phase. The heat of dilution raises the temperature rapidly to about 40°C. Further heating with steam to 120—130°C favors the hydrazine-forming reaction 28 and minimizes the competing destmctive reaction 29. The nitrogen that is formed (eq. 29) is scmbbed with water to remove ammonia and is then used as an inert pad to prevent decomposition of hydrazine during the concentration steps.  [c.282]

Charles and Gay-Lussac, working independently, found that gas pressure varied with the absolute temperature. If the volume was maintained constant, the pressure would vary in proportion to the absolute temperature [I j. Using a proportionality constant R, the relationships can be combined to form the equation of state for a perfect gas, known as the perfect gas law.  [c.15]

The ideal gas law or perfect gas law is a combination of Boyle s and Charles laws for any compressible fluid (gas/vapor).  [c.383]

Some 500 years ago during Columbuss second voyage to what are now the Americas he and his crew saw children playing with balls made from the latex of trees that grew there Later Joseph Priest ley called this material rubber to describe its ability to erase pencil marks by rubbing and in 1823 Charles Macintosh demonstrated how rubber could be used to make waterproof coats and shoes Shortly there after Michael Faraday determined an empirical for mula of CsHs for rubber It was eventually determined that rubber is a polymer of 2 methyl 1 3 butadiene  [c.408]

When sizing a cooling tower, then, the highest anticipate wet bulb should be used. During the rest of the time, the cooling tower is oversized for the duty. The exiting water temperature will simply be less than design which is typically desirable. A wet bulb chart is arranged to show the frequency of occurrence. At the Charles DeGaul Airport, for example 65 degree wet bulb is exceeded 2% of summertime hours, 68 degree wet bulb is exceeded. 5% of summertime hours, and 70 degree wet bulb is exceeded. 2% of summertime hours. Generally, the designer would select 70 degrees as the design wet bulb for a situation like this but some installations aren t critical allowing the use of a reduced design values and smaller cooling towers. Other installations may work only in the winter or at night when the wet bulb temperature is low. The designer must select the design wet bulb for the project. When in doubt, select the highest anticipated wet bulb temperature to insure satisfactory year around operation. The designer should only consider towers with independently certified capacities. The Cooling Tower Institute (CTI) lists towers that subscribe to their test standard STD-201. Alternately, the designer should specify a field test by an accredited independent test agency in accordance with CTI Acceptance Test Code ATC-105 or ASME PCT-23. Manufacturer s catalogs have cooling tower selection charts with easy to follow instructions that begin with the calculation of two values  [c.67]

Darwinian evolution and the doctrine of energy con-seiwation. In critical response to Charles Darwin s demand for a much longer time for evolution by natural selection, and in opposition to Charles Lyell s uniformitariaii geology upon which Darwin s claims were grounded, Thomson deployed Fourier s conduction law (now a special case of energy dissipation) to make order-of-magnitude estimates for the earth s age. The limited time-scale of about 100 million years (later reduced) appeared to make evolution by natural selection untenable. But the new cosmogony (theoi y of the origin of the universe) was itself evo-lutionai y, offering little or no comfort to strict biblical literalists in Victorian Britain.  [c.1138]
