However, it introduces many new concepts that are not covered at all in middle and high school, making it a very difficult subject to understand. One particularly challenging concept is that while thermodynamic quantities as state functions are independent of the path, heat and work depend on the path. This can be compared to the elevation difference in mountain climbing, which is determined only by the difference in elevation between the starting point and the destination, whereas the cost and fatigue of climbing depend on the path taken (for example, whether one drives or walks).\n   In this paper, we will examine representative reversible processes such as isothermal reversible processes, adiabatic reversible processes, isochoric reversible processes, and isobaric reversible processes. We will then consider the Carnot cycle, Stirling cycle, Otto cycle, and Diesel cycle, which are obtained through combinations of these representative reversible processes, and calculate heat, work, internal energy, enthalpy, entropy, Helmholtz energy, and Gibbs energy for each. While heat, work, internal energy, enthalpy, and entropy are described in textbooks used in universities,[1, 2] the calculations for Helmholtz energy and Gibbs energy become very complex and are often not covered. However, we will discuss these in detail\nhere.\n   Recently, the concepts of thermodynamic functions such as enthalpy and entropy have started to appear in high school chemistry textbooks. However, high school students often have only a superficial understanding, knowing only the names of the functions. We hope that this paper can contribute even slightly to helping students understand thermodynamics more deeply when they advance to university without feeling bewildered.\n   Note that in all derivations below, gases are assumed to be ideal gases.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"大学の１，２年で学ぶ熱力学は，大学の化学科では物理化学の中心をなす科目であるが，中学校，高等学校では一切学ばない新しい概念が多く登場するために非常に理解しにくい科目である。特に理解しにくいのは，熱力学量が状態関数であれば径路によらないが，熱や仕事は径路に依存するということである。これは，登山における標高差は出発点の標高と到達点の標高の差のみで決まり，登山に対するコストや疲労度は径路（例えば車で登るか歩いて登るか）によるという比喩に対応する。\n　ここでは，代表的な可逆過程である等温可逆過程，断熱可逆過程，定積可逆過程，定圧可逆過程についてそれぞれ考え，代表的な可逆過程の組み合わせによって得られるカルノーサイクル，スターリングサイクル，オットーサイクル, ディーゼルサイクルについて熱，仕事，内部エネルギー，エンタルピー，エントロピー，ヘルムホルツエネルギー，ギブズエネルギーについて求める。熱，仕事，内部エネルギー，エンタルピー，エントロピーについては大学で使用する教科書等でも記述されているが,ヘルムホルツエネルギー，ギブズエネルギーについては非常に複雑な式になるので求められてないが，ここでは詳述する。\n　最近，高等学校の化学の教科書でもエンタルピーやエントロピーの熱力学関数の概念が記述されるようになったが，関数の名前を教えらるれだけで高校生の多くは表面上の理解しかしてない。高校生が大学に進学したときに戸惑うことなく熱力学を深く理解することにこの論文が少しでも寄与できればと思う。　\n　なお，以下のすべての導出では気体は理想気体とする。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14990/0002000526","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"甲南大学","subitem_publisher_language":"ja"}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AA11561231","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"24346446","subitem_source_identifier_type":"EISSN"}]},"item_10002_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open
