I have been guilty of contributing to the eventual end of all things myself. Each morning before heading out to work, I take my heavily insulated thermos and fill it with 250 grams of ice at 0ºC and 1.5 liters of water at 20ºC. By the time I get to school, the ice has completely melted. Your task is to write a few paragraphs and some analytic calculations explaining just how awful my actions are. Be sure to answer the following questions… • Define entropy and give an example of a physical process where the entropy increases and give an example where the entropy decreases. • What does “The Entropy Death of the Universe” mean? This is sometimes referred to as “The Heat Death of the Universe”…why? • Describe the physical process of ice melting in an insulated container…
