Answer:
<em>An object is said to be rated </em><em>1 Watt </em><em>when it performs a work worth </em><em>1 Joule </em><em>in </em><em>1 second.</em>
Explanation:
<em>We know that power is rate of doing work or Work done in a given period of time.</em>
<em>Power is simply given by the formula:</em>
<em>Power=(Work)/(Time)</em>
<em>The SI unit of Power, Work and Time are Watts, Joules and Seconds respectively.</em>
<em>Hence, 1 Watt=1 Joule/ 1 Second</em>

The thermal energy of an object is the energy contained in the motion and vibration of its molecules. Thermal energy is measured through temperature. The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.
