thermodynamics cTopic Branches Equilibrium Thermodynamics is the systematic study of transformations of matter and energy in systems as they approach equilibrium. The word equilibrium implies a state of balance. Equilibrium thermodynamics, in origins, derives from analysis of the Carnot cycle . Here, typically a system, as cylinder of gas, is set out of balance via heat input from a combustion combustion reaction . Then, through a series of steps, as the system settles into its final equilibrium state, work is extracted. In an equilibrium state there are no unbalanced thermodynamic potential potentials , or driving forces, within the system. A central aim in equilibrium thermodynamics is given a system in a well defined initial state thermodynamic state , subject to accurately specified constraints, to calculate what the state of the system will be once it has reached equilibrium. An equilibrium state is obtained by seeking the extrema of a thermodynamic potential function, whose nature depends on the constraints imposed on the system. For example, a chemical reaction at constant temperature ... of their entropy .

for the general geometric concept volume Thermodynamics cTopic List of thermodynamic properties System properties In thermodynamics , the volume of a thermodynamic system system is an important extensive parameter for describing its thermodynamic state . The specific volume , an intensive property , is the system s volume per unit of mass. Volume is a function of state and is inter dependant with other thermodynamic properties such as pressure and thermodynamic temperature temperature . For example, volume is related to the pressure and thermodynamic temperature temperature of an ideal gas by the ideal gas law . The physical volume of a system may or may not coincide with a control volume used to analyze the system. Overview The volume of a thermodynamic system typically refers to the volume of the working fluid, such as, for example, the fluid within a piston. Changes to this volume may be made through an application of work thermodynamics work , or may be used to produce work. An isochoric process however operates at a constant volume, thus no work can be produced. Many other thermodynamic process es will result in a change in volume. A polytropic process , in particular, causes changes to the system so that the quantity math pV n math is constant where math p math is pressure, math V math is volume, and math n math is the polytropic index , a constant .

Refimprove date April 2007 In thermodynamics, a component is a chemically distinct constituent of a system. Calculating the number of components in a system is necessary, for example, when applying Gibbs phase rule in determination of the number of degrees of freedom physics and chemistry degrees of freedom of a system. The number of components is equal to the number of independent chemical constituents, minus the number of chemical reactions between them, minus the number of any constraints like charge neutrality or balance of molar quantities . For example, a system that contains water in liquid state also contains hydronium cations and hydroxyl anions according to the reaction 2H sub 2 sub O H sub 3 sub O sup sup OH sup sup The number of components in such a system is 3 independent chemical constituents 1 chemical reaction 1 constraint charge neutrality 1. The reactions that are included in the calculations are only those reactions that actually occur not those that might occur under different conditions like higher temperature or the presence of a catalyst. The components of a system are those chemical constituents whose concentration may be varied independently in the various phases. ref Physical Chemistry 7th Edition by Peter Atkins and Julio de Paula Page 193 195 ref References references Category Chemical thermodynamics hu Komponens k mia nl Component scheikunde ... more details

orphan date August 2010 The thermodynamics of the universe is dictated by which form of energy dominates it relativistic particle s which are referred to as radiation , or non relativistic particles which are referred to as matter. The former are particles whose rest mass is zero or negligible compared to their energy, and therefore move at the speed of light or very close to it The latter are particles whose kinetic energy is much lower than their rest mass and therefore move much slower than the speed of light. The intermediate case is not treated well analytic solution analytically .

Then by the first law of thermodynamics math 0 dQ dU P dV math Where math Q math is the total heat which is assumed to be constant, math U math is the internal energy of the matter and radiation in the universe, math P math is the pressure and math V math the volume.

Unreferenced date December 2008 An atmospheric waveguide is an Earth s atmosphere atmospheric Fluid dynamics flow feature that improves the propagation of certain atmospheric wave s. The effect arises because wave parameters such as group velocity or vertical wavenumber depend on mean flow direction and strength. Thus, for instance, westerly wind westerlies might be a good waveguide for east ward traveling waves, but might strongly dissipation dissipate west ward traveling waves, by increasing or decreasing their vertical wavenumber, respectively. Modification of the waves group velocity will change their meridional propagation speed, directing them more geographical pole polewards or more equator wards. Category Atmosphere ... more details
An atmospheric wave is a periodic disturbance in the fields of atmospheric variables like surface pressure or geopotential height , temperature , or wind velocity which may either propagate traveling wave or not standing wave . Atmospheric waves range in spatial and Time temporal scale from large scale planetary waves Rossby wave s to minute sound wave s. Atmospheric waves with periods which are harmonics of 1 solar day e.g. 24 hours, 12 hours, 8 hours... etc are known as atmospheric tide s. Causes and effects The mechanism for the forcing of the wave, for example the generation of the initial or prolonged disturbance in the atmospheric variables, can vary. Generally, waves are either excited by heating or Dynamics mechanics dynamic effects, for example the obstruction of the flow by mountain ranges like the Rocky Mountains in the United States U.S. or the Alps in Europe . Heating effects can be small scale like the generation of gravity wave s by convection or large scale the formation of Rossby waves by the temperature contrasts between continents and oceans in the Northern hemisphere winter . Atmospheric waves transport momentum , which is fed back into the background flow as the wave dissipates . This wave forcing of the flow is particularly important in the stratosphere , where this momentum deposition by planetary scale Rossby waves gives rise to sudden stratospheric warming s and the deposition by gravity waves gives rise to the quasi biennial oscillation . In the mathematical description of atmospheric waves, spherical harmonics are used. When considering a section of a wave along a latitude circle, this is equivalent to a sinusoidal shape.

Image Atmosphericnoise.PNG thumb right 400px Amount of atmospheric noise for LF, MF, and HF spectrum according CCIR 322 Atmospheric noise is radio noise caused by natural atmospheric processes, primarily lightning discharges in thunderstorms. It is mainly caused by cloud to ground flashes as the current is much stronger than for Lightning Cloud to cloud lightning cloud to cloud flashes. On a worldwide scale, eight million lightning flashes occur daily. This is about 100 lightning flashes per second. The sum of all these lightning flashes results in atmospheric noise. It can be observed ref Sample of atmospheric noise url http www.ycars.org EFRA audio 20files atmospheric 20noise.mp3 ref with a radio receiver in the form of a combination of white noise coming from distant thunderstorms and impulse noise coming from a near thunderstorm . The power sum varies with seasons and nearness of thunderstorm centers. Although lightning has a broad spectrum emission, its noise power increases with decreasing frequency. Therefore, at Very Low Frequency and Low frequency , atmospheric noise often dominates, while at High Frequency , man made noise dominates in rural areas. From 1960s to 1980s, a worldwide effort was made to measure the atmospheric noise and variations. This has been documented in the CCIR 322 ref CCIR Report 322 Noise Variation Parameters url http www.spawar.navy.mil sti publications pubs td 2813 ref publication. CCIR 322 provided seasonal world maps showing the expected values of the atmospheric noise figure F sub a sub at 1 MHz during four hour blocks of the day. Another set of charts relates the F sub a sub at 1 MHz to other frequencies. CCIR Report 322 has ... P.372 en ref publication.
