In the physical sciences, quantum thermodynamics is the study of heat and Work thermodynamics work dynamics in quantum systems. Approximately, quantum thermodynamics attempts to combine thermodynamics and quantum mechanics into a coherent whole.

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 .

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

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 .

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 . Energy density in the expanding universe If the universe is not undergoing a phase transition , one can approximate its thermodynamics by neglecting interactions between particles, and assuming all the energy is in the form of heat . 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.

distinguish Heat bath Unreferenced auto yes date December 2009 In thermodynamics and statistical mechanics , a thermal bath is a reservoir of particles at finite temperature undergoing Brownian motion , and that in thermal contact with an object of interest. Because of its nonzero temperature, this system contains thermal energy . This yields an environment where the fluctuations due to Fluctuation dissipation theorem thermal noise are significant. This type of environment can have important effects at a molecular scale, such as for the operation of molecular motors or Nucleic acid double helix DNA stretching stretching of DNA molecules.

In thermodynamics , a critical line is the higher dimensional equivalent of a Critical point thermodynamics critical point ref B. Windom, Theory of Phase Equilibrium , J. Phys. Chem 1996 , 13190 13199 ref . It is the locus of contiguous critical points in a phase diagram . These lines cannot occur for a single substance due to the Gibbs phase rule phase rule , but they can be observed in systems with more variables, such as mixtures. Two critical lines may meet and terminate in a tricritical point . References references States of matter Category Thermodynamics Category Critical phenomena ... more details
to criminality. Biological determinism also biologism is the interpretation of humans and human life from a strictly biological point of view, and it is closely related to genetic determinism . Another definition is that biological determinism is the hypothesis that biological factors such as an organism ... taste in music , committing murder , or writing poetry . A biological determinist would posit that such behaviours, and personality traits in general, are mediated primarily by biological factors, such as genotype genetic makeup . An extreme variant of biological determinism might assert that an organism s behavior is determined entirely by biological factors, and that all of these factors are innate to that organism e.g. DNA . By asserting that biological factors are the primary determinants of behaviour, biological determinism implies of course that non biological factors, such as social convention ..., a variant of biological determinism might consider non innate biological factors, such as the biological ... innate biological factors. Biologists sometimes regard a charge of biological determinism as a straw man , as there is currently no support for strict biological determinism in the field of genetics ... of biological determinism.
