The principle of conservation of energy seemed to describe only certain kinds of mechanical systems. Mid-19th-century <span style=\"color: #ff0000\"><strong>experiments<\/strong><\/span> <strong>performed<\/strong> by Englishman <span style=\"color: #ff0000\"><strong>James Joule<\/strong><\/span> and others, however, showed a <strong>strong connection<\/strong> between the <strong><span style=\"color: #333399\">transfer of energy by heat in thermal processes<\/span><\/strong> and the <strong><span style=\"color: #333399\">transfer of energy by work in mechanical processes<\/span><\/strong>. Today we know that mechanical energy can be transformed to internal energy, which is formally defined in this chapter. Once the concept of energy was generalized from mechanics to include internal energy, the <strong><span style=\"color: #333399\">principle of conservation of energy<\/span><\/strong> emerged as a <strong><span style=\"color: #ff00ff\">universal law of nature<\/span><\/strong>.<\/p>\n<p style=\"text-align: justify\">This session focuses on the concept of internal energy, the <strong><span style=\"color: #333399\">first law of thermodynamics<\/span><\/strong>, and some important <strong><span style=\"color: #333399\">applications<\/span><\/strong> of the first law. The first law of thermodynamics describes systems in which the only energy change is that of internal energy and the transfers of energy are by heat and work. A major difference in our discussion of work in this chapter from that in most of the chapters on mechanics is that we will consider <strong>work done on deformable systems<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Raymond A.
