The bold heights of the Coast Range force the nearly or quite saturated air of the sea-wind to rise abruptly several thousand feet, and the adiabatic cooling creates fog, cloud, and even rain on the seaward slope of the mountains.
This added to the isothermal strain produced by dS will give the whole adiabatic strain.
The third operation is an isothermal compression, CD, until the volume and pressure are such that an adiabatic compression DA will just bring the substance back to the original state.
The second operation is an adiabatic expansion, BC, in which the volume is further increased and the temperature sinks by dt to the temperature of the refrigerator.
As an example ofadiabatic change, a sudden extension of the wire already referred to by an increase of stress dS may be considered.
Carnot cycle consisting of two isothermal and two adiabatic changes.
Any small step of change of a substance may be regarded as made up of a step of volume, say, followed by a step of temperature, that is, by an isothermal step followed by an adiabatic step.
But let us assume that we have a compressor which shows an adiabatic pressure line.
Following this adiabatic curve until it intersects line No.
We find this by following down the first line intersected by the adiabatic curve to the point where the zero heat curve intersects this same line, the reading being given in figures to the left immediately opposite.
Beginning with the adiabatic curve, we find that for one volume of air when compressed without cooling the curve intersects the first vertical line at a point between 0.
In this cycle adiabatic compression is assumed to raise the temperature of the working fluid from the lowest to the highest point.
When the heat supply ceases, adiabatic expansion proceeds and reduces the pressure of the working fluid from the higher to the lower point.
In this cycle adiabatic compression raises the pressure--not the temperature--from the lower to the higher limit.
This is the ratio of the adiabatic elasticity of air to the isothermal elasticity.
The ratio of the adiabatic to the isothermal elasticity, required for calculating the velocity of sound, is therefore the same as the ratio of the specific heat at constant pressure to that at constant volume.
To reconcile the observed and calculated values of the velocity, the increase of pressure in adiabatic compression must be 1.
In consequence of this assumption, the formulae he obtained for adiabatic expansion were necessarily wrong, but no data existed at that time for testing them.
For all these reasons, it would be interesting to examine the known aggregates, to seek to account for the law of the densities, and to see if it is the adiabatic law of gases.
A question comes here: I have spoken of the adiabatic law, but this law is not the same for all gases, since it depends upon the ratio of their two specific heats; for the air and like gases, this ratio is 1.
We may therefore rather compare an aggregate to a gas in adiabatic equilibrium, which takes the spherical form because this is the figure of equilibrium of a gaseous mass.
This fusion and evaporation of the ice by its transformation of latent, to sensible, heat, in a measure counteracts, and so retards, the adiabatic elevation of temperature within the column.
The moisture congealed in the cirrus clouds floating in the uppermost layer of the convective zone, is carried down in this vortex and first melted and in turn evaporated, due to the adiabatic effect.
As applied to moisture-laden and near-surface winds, the effective agents of adiabatic cooling are the upland areas upon the continents, and especially the ranges of mountains.
The adiabatic lines, representing a fall of temperature of 1 deg.
It falls at a slower rate in the cloud, the rate probably being that computed by physicists as the adiabatic rate for air in which condensation is taking place.
The temperature followed the normal change, which is as follows: during the day, up to a certain height, which varies under different conditions, there is a decrease nearly at the adiabatic rate of 1 deg.
The straight dotted lines show the adiabatic decrease of temperature for ascending dry air.
The continuous line, representing the day observations, shows a uniform fall of temperature at the adiabatic rate to the cloud level.
This curve shows that with increasing altitude the temperature falls uniformly during the day and approximately at the adiabatic rate represented by the dotted lines.
Higher than this, the temperature decreases at a fairly uniform rate, but more slowly than the adiabatic rate.
During the day there is a decrease of temperature at the adiabatic rate (1 deg.
This air, cooling by expansion at the adiabatic rate, will rise to about 440 metres before it assumes the mean temperature of the upper air column.
This should cause a fall of temperature at the adiabaticrate from the ground to the top of the colder current, and is probably the origin of the "cold wave" shown in Type 5.
The temperature decreased rapidly at first, then moderately up to three miles, and above that it fell almost at the adiabatic rate.
This is called the "adiabatic rate of change of temperature," because it is produced by an alteration in the density of the air, due to variation in pressure, without the addition or loss of heat.
From this it would follow that every adiabatic expansion, provided it be sufficiently continued, will bring such substances into the heterogeneous region, i.
Those conditions being fulfilled, we may, simply by adiabatic expansion, not only lower the temperature of some substances down to T3, but also convert them into the liquid state.
Cailletet and Pictet have availed themselves of this adiabatic expansion for condensing some permanent gases, and it must also be used when, in the cascade method, T3 of one of the gases lies above Tc of the next.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "adiabatic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
