Definition: The word "adiathermic" refers to a gas in which the pressure increases with increasing temperature. The term has several definitions depending on context, but the most common one is: "a gas that expands under increased pressure as its temperature increases." In general, adiathermic gases are substances whose properties change with an increase in temperature. This is because they expand to fill more volume than their original size at higher temperatures and decrease their density. The expansion of a substance typically occurs due to the action of heat, which increases the temperature. Adiathermic gases are not always found only in chemical reactions; they can also form in many natural processes, such as in the formation of ice in cold climates or in the process of chemical digestion in the digestive system. However, adiathermic gases are rare and usually occur under specific conditions that cannot be easily recreated. Overall, adiathermic gases have a wide range of applications, from scientific experiments to practical engineering and manufacturing processes.
