The illustrious question by German Astrophysicist R. Emden, “Why do we have winter heating?” has been re-examined for air following both the ideal and imperfect gas laws; the internal energy of the air in the room remains unaffected in the former case whereas it increases marginally for the latter one. The findings corresponding to ideal gas law were correlated by Emden with the mass of a person which does not change even though food is constantly consumed. This example corresponds to adulthood when the mass of a person remains more or less constant. But the marginal change of internal energy in the case of van der Waals gas is consistent with three stages of a person — initially a person grows during childhood followed by adulthood when he has more or less constant weight and finally in old age, it deteriorates.

This chapter brings together, and builds on, the results from previous chapters to provide a succinct, and comprehensive, summary of all key relationships relating to ideal gases, including the heat and work associated with isothermal, adiabatic, isochoric and isobaric changes, and the properties of an ideal gas’s heat capacities at constant volume and constant pressure. The chapter also has two ‘case studies’ which use the ideal gas equations in broader, and more real, contexts, so showing how the equations can be used to tackle, successfully, more extensive systems. The first ‘case study’ is the Carnot cycle, and so covers all the fundamentals required for the proof of the existence of entropy as a state function; the second ‘case study’ is the ‘thermodynamic pendulum’ – a system in which a piston in an enclosed cylinder oscillates to and fro like a pendulum under gravity, in both the absence, and presence, of friction.

This chapter details Dmitrii Mendeleev's turn to gas laws. In 1871, Mendeleev's successes lay far in the future. However, his bold predictions of 1871 had two glaring deficiencies: they were unsubstantiated, and they were not in the chemical tradition. The whole thing smacked of physics, and, as the chemist abandoned his half-hearted attempts to uncover his missing elements, his wavering attention shifted to that science. In the eyes of his peers, Mendeleev had abandoned his chemical guesses—and chemistry altogether—in favor of subsidized research on gas laws, of all things. This new, broadly conceived gas project would dominate his attention throughout the 1870s, but, in contrast to the repeated successes of the periodic law, every aspect of the effort would end in dramatic failure.

The Ideal

The condition for maximum specific work from a gas-turbine engine operated on a Joule cycle is generalized to ideal gases from the well-known result obtained by using a perfect gas. An obvious corollary is shown to be the principal theorem, when the working substance is an ideal gas with specific heat capacities varying with temperature, that the turbine outlet and compressor outlet temperatures are equal. Two additional corollaries are shown to hold in general. A simple study shows that the optimum condition point is not much affected by real departures from reversible behaviour. The condition for which a regenerative heat exchanger is then desirable is found. The results are generalized to any gas for which the enthalpy is a function of temperature only.

Gas Laws summarizes the general laws that describe how the volume of a gas changes in response to changes in pressure (P), temperature (T in Kelvin) or the number of moles (n). The ideal gas law, which combines Boyle’s law, Charles’s law and Avogadro’s law, is presented, with explanations of using it to solve gas-law problems. Mathematical rearrangements of the ideal gas law to determine density and molar mass are described along with the use of Dalton’s law of partial pressures to find the pressure of each gas in a mixture. Finally the chapter presents ideal gas law and reaction stoichiometry, Graham’s law of effusion, and basic notions of real gases and their deviation from the ideal gas laws.

In this study, we fabricated the experimental equipment for testing gas laws, using eco-friendly and easy-to-find materials. The equipment was able to test, with relatively high accuracy (error less than 1%), the gas laws and demonstrate the state equation of ideal gases. The findings reveal that the equipment and similar experiments can be adopted for teachers’ modeling activities as well as students’ experiments, or teachers can guide their students to fabricate their own equipment as a STEM experience while teaching the topic “Ideal Gas” – Grade 12 Physics, the national high school program 2018.

In investigations involving gases at high pressures it is as essential to know the relative densities of the media concerned as it is their actual pressures. This demands a knowledge of the deviations from the ideal gas laws over wide ranges of pressure and temperature for each particular medium. Although reliable data are available for the commoner single gases, with perhaps the exception of carbon monoxide, as yet little is known concerning the compressibility of mixtures, except generally that neither the Law of Partial Pressures nor the Law of Additive Volumes is strictly obeyed. In this connection the recent researches of Masson, Verschoyle, Bartlett, Keyes and their co-workers have been very informative, yet a great deal more work needs to be done before such lacunæ in our knowledge of such matters are filled.

An energy analysis of the processes of obtaining and using artificial cold in chemical technology is presented. The most well-known methods of obtaining and applying the cooling effect are considered: adiabatic expansion of vapor and gaseous bodies in expanders, throttling. Special attention is paid to the effect of object deviation from the ideal gas model.
