Did you read all of Chapter Did you read all of Chapter 18 18 for today? for today? a) a) Yes Yes b) b) No No Transforming Energy s The Industrial Revolution was driven by the invention of the steam engine. • They changed chemical potential energy to kinetic energy via heat. • But how efficient could they be? Limits to efficiency s Energy can be completely converted into heat ost all kinetic energy • Most all kinetic energy ends up as heat eventually. s But heat c a n n o t be completely converted into kinetic energy. Some will always remain as heat. The Law of Increasing Disorder s This tendency led to the discovery of the Second Law of Thermodynamics, the Law of Increasing Disorder or he Law if Increasing Entropy: The Law if Increasing Entropy: s Processes occurring naturally, without the addition of outside energy, end with the same, or greater, disorder than they began. Example of a heat process: Which picture came first?...
