Example for Laws of Thermodynamics
During the first oil crisis of the early 1970s, a business entrepreneur placed an expensive full-page advertisement in the New York Times, appealing to "the ingenuity of the American people." He offered a cash reward to any inventor who could "raise the temperature of a metal rod by cooling a second rod" and then "generate power by tapping the difference in temperatures."
Use your knowledge of thermodynamics to explain why nobody ever won the reward. Be specific.View Full Posting Details
