The Nernst postulate identifies the isotherm T = 0 as coincident with the adiabat S = 0, although other isotherms and adiabats are distinct.

# If isotherms are concave towards the " north-east " direction ( 45 °), then adiabats are concave towards the " east north-east " ( 31 °).

# If adiabats and isotherms are graphed severally at regular changes of entropy and temperature, respectively ( like altitude on a contour map ), then as the eye moves towards the axes ( towards the south-west ), it sees the density of isotherms stay constant, but it sees the density of adiabats grow.

Warm fronts are at the trailing edge of the temperature increase, which is located on the equatorward edge of the gradient in isotherms, and lie within broader troughs of low pressure than cold fronts.

In this image, red lines are Contour line # Temperature and related subjects | isotherms, solid green lines are the potential temperature, and dashed green lines are the equivalent potential temperature ; these three all use the temperature scale at the horizontal 1000 mb level near the bottom.

However, when the compressibility factors of various single-component gases are graphed versus pressure along with temperature isotherms many of the graphs exhibit similar isotherm shapes.

In the tephigram, isotherms are straight and have a 45 degree inclination to the right while isobars are horizontal and have a slight curve.

The following diagram is a P-V diagram with a superposition of adiabats and isotherms:

In 1947, N. Herlofson proposed a modification to the emagram which allows straight, horizontal isobars, and provides for a large angle between isotherms and dry adiabats, similar to that in the tephigram.

Because the process takes advantage of the nonlinearity of the isotherms, a larger column feed can be separated on a given column with the purified components recovered at significantly higher concentrations.

Properties of surface chemicals can be investigated by measuring pressure / area isotherms, as the two-dimensional analog of Boyle's law,, at constant temperature.

Once a map has a field of station models plotted, the analyzing isobars ( lines of equal pressure ), isallobars ( lines of equal pressure change ), isotherms ( lines of equal temperature ), and isotachs ( lines of equal wind speed ) can be easily accomplished.

Because the process takes advantage of the nonlinearity of the isotherms, a larger column feed can be separated on a given column with the purified components recovered at significantly higher concentration.

The van der Waals isotherms: the model correctly predicts a mostly incompressible liquid phase, but the oscillations in the phase transition zone do not fit experimental data.

Adsorption is usually described through isotherms, that is, the amount of adsorbate on the adsorbent as a function of its pressure ( if gas ) or concentration ( if liquid ) at constant temperature.

It is common in middle and northern temperate and boreal latitudes of Europe, between the July isotherms, and thus predominantly in cooler climates than the Firecrest.

Its range lies between the July isotherms.

Maps using isotherms show temperature gradients, which can help locate weather fronts.

By plotting the freezing line, isotherms can be useful in determination of precipitation type.

Fig. 3 pV-diagram of the ideal Stirling cycle. In the pV diagram ( Fig. 3 ) the corresponding cycle consists of two isotherms and two isochores.

Climatically it lives between the 0 ° C and 20 ° C isotherms.

This part of the freeze-drying process is governed by the material ’ s adsorption isotherms.

The codes in the red box -- there are several of them covering various contingencies -- are contained in a sealed X-ray-proof `` unique device ''.

Thus Burns's `` My love is like a red, red rose '' and Hopkins' `` The thunder-purple sea-beach, plumed purple of Thunder '' although clearly intelligible in content, hardly present ideas of the sort with which we are here concerned.

Interlocking signals are normally at stop or `` red '' position, and a lever must be pulled to `` clear '' the signal.

Inside, the walls are covered with blue and white tile, the floor with red and cream carpets.

The red sables are 8 ; ;

The video signal is amplified and then switched, in synchronism with the three ultraviolet light sources which are sequenced by the rotating mirror so that during one-twentieth of a second only one wavelength, corresponding to red, green, or blue, is seen.

This does not mean, though, that a red wine improves with prolonged aeration: there is a reasonable limit -- and wines kept over to the next meal or the next day, after they have once been opened, are never as good.

A few red wines, notably those of the Beaujolais, are better consumed at cellar temperature.

Though there are many exceptions, which we have noted in preceding pages, white wine is as a rule best consumed between two and six years old, and red wines, nowadays, between three and ten.

The red pills are a vitamin-and-iron compound.

The immature fruits are yellow, the ripe ones red.

The sub-umbellate inflorescences are borne at the end of long stems, having numerous bright red flowers, which are radially symmetric with inferior ovaries.

For example the standard glutamic acid ( glutamate ) and the non-standard gamma-amino acid gamma-amino-butyric acid ( GABA ) are respectively the brain's main excitatory and inhibitory neurotransmitters, hydroxyproline-a major component of the connective tissue collagen-is synthesised from proline, the standard amino acid glycine is used to synthesise porphyrins used in red blood cells, and the non-standard carnitine is used in lipid transport.

North of the mineral region is the Cereal Belt, embracing the Tennessee Valley and the counties beyond, whose richest soils are the red clays and dark loams of the river valley ; north of which are less fertile soils, produced by siliceous and sandstone formations.

The adults are herbivorous and feed with their rhipidoglossan radula on macroalgae, preferring red or brown algae.

Only red abalone may be taken ; black, white, pink, and flat abalone are protected by law.

The largest species are red alder ( A. rubra ) on the west coast of North America, and black alder ( A. glutinosa ), native to most of Europe and widely introduced elsewhere, both reaching over 30 m. By contrast, the widespread Alnus viridis ( green alder ) is rarely more than a 5 m tall shrub.

The peoples of the Tarim Basin in northern China are now known to be Caucasian and there were widespread attempts to keep western archeologists from testing samples such as deliberately replacing the mummies or decapitating them, even defacing ancient cave painting depictions of these people with large amounts of body hair and features such as red colored hair and blue eyes.

Approximately 60 species are recognized, with inflorescences and foliage ranging from purple and red to green or gold.
