<p>The <b>law of conservation of energy</b> states that the total <a href="page.php?w=energy">energy</a> of an <a href="page.php?w=isolated_system">isolated system</a> remains constant; it is said to be <a href="page.php?w=Conservation_law">''conserved''</a> over time. In the case of a <a href="page.php?w=Closed_system">closed system</a>, the principle says that the total amount of energy within the system can only be changed through energy entering or leaving the system. Energy can neither be created nor destroyed; rather, it can only be transformed</p><p>
