Carnot efficiency is a useful tool to quickly estimate possible efficiency for different situations. A lecture- demonstration Stirting engine runs on heat from a hot cup of coffee at 350 K; assume the applicable tow temperature thermal reservoir is at the approximate room temperature 300 K. Estimate the Carnot efficiency.
