## Isothermal Sentence Examples

**isothermal**corresponding to the temperature 0', and AD a neighbouring**isothermal**0". - It is often impossible to observe the pressure-coefficient dp/de directly, but it may be deduced from the
**isothermal**compressibility by means of the geometrically obvious relation, BE = (BEÃ†C) XEC. The ratio BEÃ†C of the diminution of pressure to the increase of volume at constant temperature, or - dp/dv, is readily observed. - I by the whole area B"DZ'VO under the
**isothermal**9"D and the adiabatic DZ', bounded by the axes of pressure and volume. - The difference 90-E is represented by the area 9"DdO to the left of the isometric Dd under the

**isothermal**lines of 60° F. - A cycle such as ABCD enclosed by parts of two
, BC, AD, and two adiabatics, AB, CD, is the simplest form of cycle for theoretical purposes, since all the heat absorbed, H', is taken in during the process represented by one**isothermals****isothermal**at the temperature o', and all the heat rejected, H", is given out during the process represented by the other at the temperature 0". - Taking this ideal limit as a theoretical or absolute zero, the value of H may be represented on the diagram by the whole area included between the two adiabatics BAZ, CDZ' down to the points where they intersect the
**isothermal**of absolute zero, or the zero isopiestic OV asymptotically at infinity. - Applying the above equation to a gas obeying the law pv=RT, for which the work done in
**isothermal**expansion from a volume i to a volume r is W=RT loger, whence dW=R log e rdt, he deduced the expression for the heat absorbed by a gas in**isothermal**expansion H=R log er/F'(t). - Done by a gas in
**isothermal**expansion is assumed to be equivalent or proportional to the heat absorbed, H=R log e r/F'(t). - This most fundamental point was finally settled by a more delicate test, devised by Lord Kelvin, and carried out in conjunction with Joule (1854), which showed that the fundamental assumption W =H in
**isothermal**expansion was very nearly true for permanent gases, and that F'(t) must therefore vary very nearly as J/T. - Let BE be an isometric through B meeting AD in E, and EC an isopiestic through E meeting BC in C. Let BA, CD be adiabatics through B and C meeting the
**isothermal**0" in A and D. - Then by relations (2) the heat, H, absorbed in the
**isothermal**change BC, is to the work, W, done in the cycle ABCD in the ratio of o to (o' - o"). - (I) The heat, H, absorbed in
**isothermal**expansion (latent heat of expansion) from p to p" is equal to the diminution of pressure (p' - p”) multiplied by the absolute temperature and by the expansion per degree (v" - v')/(o' - o") at constant pressure. - (2) The heat, H, absorbed in
**isothermal**expansion from v to v" is equal to the increase of volume (v" - v') multiplied by the absolute temperature, and by the increase of pressure per degree (p' - p")/(o' - o"), at constant volume. - EF is the change of volume corresponding to a change of pressure BE when no heat is allowed to escape and the path is the adiabatic BF, EC is the change of volume for the same change of pressure BE when the path is the
**isothermal**BC. These changes of volume are directly as the compressibilities, or inversely as the elasticities. - If we write K for the adiabatic elasticity, and k for the
**isothermal**elasticity, we obtain S/s = ECÃ†F = K/k. - 2, may be found by adding to the heat required for the change of temperature at constant volume, sdo, or at constant pressure, Sdo, the heat absorbed in
**isothermal**expansion as given by relations (4). - It is generally convenient to divide the path into two steps,
**isothermal**and isometric, or**isothermal**and isopiestic, and to integrate along each separately. - The
**isothermal**elasticity - v(dp/dv) is equal to the pressure p. The adiabatic elasticity is equal to y p, where -y is the ratio S/s of the specific heats. - Joule failed to observe any change of temperature in his apparatus, and was therefore justified in assuming that the increase of intrinsic energy of a gas in
**isothermal**expansion was very small, and that the absorption of heat observed in a similar experiment in which the gas was allowed to do external work by expanding against the atmospheric pressure was equivalent to the external work done. - The increment of this area (or the decrement of the negative area E--04) at constant temperature represents the external work obtainable from the substance in
**isothermal**expansion, in the same way that the decrement of the intrinsic energy represents the work done in adiabatic expansion. - The function G is represented by the negative area D"DM under the
**isothermal**, bounded by the isopiestic DM and the axis of pressure. - K, k, Adiabatic and
**isothermal**elasticities. - The
**isothermal**lines trend from south-east to north-west. - The
**isothermal**lines, in fact, suggest that in the vast area of the Pacific something corresponding to the " planetary circulation " is established, further investigation of which may be of extreme value in relation to current inquiries concerning the upper air. - A continual circulation might thus be set up in an
**isothermal**enclosure and maintained with the performance of an unlimited supply of work. - In considering the corresponding relation for a solution instead of a pure liquid, possible differences in concentration make the column method difficult of application, and it is better to attach the problem by means of an imaginary cycle of
**isothermal**operation. - The available energy A is the work which may be gained from the system by a small reversible
**isothermal**operation with an osmotic cylinder, that is Pdv. - Thus, the tiger ranges from the equator to northern Asia as far as the river Amur, and to the
**isothermal**of 32° Fahr. - These
**isothermal**lines will be found to vary frommonth to month over the two hemispheres, or over local areas, during summer and winter, and their position is modified by continental or oceanic conditions. - The stages at which heat is taken from the furnace and rejected to the cooler (C) are approximately
**isothermal**at the upper and lower limits of temperature respectively, and the cycle accordingly is approximately "perfect" in the thermodynamic sense. - The theoretical indicator diagram is made up of two
**isothermal**lines for the taking in and rejection of heat, and two lines of constant volume for the two passages through the regenerator. - It was then discharged through the regenerator, depositing heat for the next charge of air in turn to take up. The indicator diagram approximated to a form made up of two
**isothermal**lines and two lines of constant pressure. - The Peculiar Advantage Of The Electric Method Of Callendar And Barnes, Already Referred To, Is That The Specific Heat Itself Is Determined Over A Range Of 8° To 10° At Each Point, By Adding Accurately Measured Quantities Of Heat To The Water At The Desired Temperature In An
**Isothermal**Enclosure, Under Perfectly Steady Conditions, Without Any Possibility Of Evaporation Or Loss Of Heat In Transference.
