First Law of Thermodynamics - an overview | ScienceDirect Topics

The First Law of Thermodynamics evolved from the experimental demonstration that heat and mechanical work are interchangeable forms of energy. From: Physical Chemistry, 2017 Bahman Zohuri, in Physics of Cryogenics, 2018 The first law of thermodynamics is generally thought to be the least demanding to grasp, as it is an extension of the law of conservation of energy, meaning that energy can be neither created nor destroyed. However much energy there was at the start of the universe, there will be that amount at the end. However, thermodynamics is a subtle subject, and the first law is much more interesting than this remark might suggest. Moreover, like the zeroth law, which provided an impetus for the introduction of the property “temperature” and its clarification, the first law motivates the introduction and helps to clarify the meaning of the elusive concept of “energy.” Energy balance, based on the first law of thermodynamics, is developed to better understand any process, to facili
