The 1st law of thermodynamics With these investigations, decisive preliminary work was done at the same time for the formulation of the general law of conservation of energy -
domyhomework club, which states that energy can neither be created nor lost, but can only be transformed from one form of energy into other forms of energy or transferred from one body to other bodies. Later, after the law of conservation of energy was generally accepted, the "equals" sign was replaced by the equals sign. Today, we have difficulty even understanding the problem of that time, since we now only measure energy in one unit -

chemistry question solver , many physicists dealt with the problem of the connection between heat and work, and between different areas of nature in general. In addition to Joule, these included e.g. Julius Robert Mayer, Hermann Von Helmholtz and Benjamin Thompson (Count Rumford). Four reasons can be given for the fact that at this time so many researchers found the basic ideas of the law of conservation of energy and thus also of the 1st law of thermodynamics as a form of the law of conservation of energy: - the discovery of the connection between different fields of physics; - the tendency to trace everything back to mechanics as a continuation of
Newton's ideas; - the (subsequent) scientific analysis of the steam engine; - the search for a unified fundamental principle of nature. Useful Resources:
