The inventor proposed the revolutionary design of the new engine based on the heat stored in the ocean. The inventor plan is to mount it on a boat in San Francisco and set off on a journey across the Pacific Ocean. Heat is extracted from the ocean, which acts is a single heat reservoir, and it is converted entirely to work in the form of a rapidly rotating propeller. The ocean is huge and the decrease in its temperature as a result of withdrawing heat is negligible. By the time the inventor arrive in Japan, not a gram of diesel fuel will be used, because all the heat needed to power the boat has been extracted from the ocean. Is this scenario possible? Explain from the thermodynamic point of view.
use the concept mof electron configuration to explain why the number of valence electrons in metals tend to be less the number in most nonmetals.
