e. Gas exchange is the physical process by which gases move passively by diffusion across a surface. For example, this surface might be the air/water interface of a water body, the surface of a gas bubble in a liquid, a gas-permeable membrane, or a biological membrane that forms the boundary between an organism and its extracellular environment.
The Natural Gas Act of 1938 had an enormous impact on the future of not only the interstate natural gas market, but the U.S. energy policy and regulation. The natural gas industry has undergone tremendous change since 1938, and pipeline companies no longer function as resellers of gas to local distribution companies (LDCs), the ideas behind the ...
e. The first law of thermodynamics is a formulation of the law of conservation of energy in the context of thermodynamic processes. The law distinguishes two principal forms of energy transfer, heat and thermodynamic work, that modify a thermodynamic system containing a constant amount of matter. The law also defines the internal energy of a ...
Rationing is the controlled distribution of scarce resources, goods, or services, or an artificial restriction of demand. Rationing controls the size of the ration, which is one person's allotted portion of the resources being distributed on a particular day or at a particular time. Rationing in the United States was introduced in stages during ...
The van der Waals equation, named for its originator, the Dutch physicist Johannes Diderik van der Waals, is an equation of state that extends the ideal gas law to include the non-zero size of gas molecules and the interactions between them (both of which depend on the specific substance). As a result the equation is able to model the phase ...
The laws describing the behaviour of gases under fixed pressure, volume, amount of gas, and absolute temperature conditions are called Gas Laws.The basic gas laws were discovered by the end of the 18th century when scientists found out that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.
Charles' law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles' law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. [ 1]
Case law in the UK and the US clearly held though, the construction and operation of a gas-works was not the creation of a public nuisance or malum in se, due to the reputation of gas-works as highly undesirable neighbors, and the noxious pollution known to issue from such, especially in the early days of manufactured gas, gas-works were on ...
