METEO 300 Lecture Notes - Lecture 22: Spontaneous Process, Thermodynamics
Document Summary
Me 300 - lecture 22 - second law of thermodynamics. Entropy: a measure of the randomness of atoms. The tea gets colder, while the room heats up a very small amount. *heat from the tea can spontaneously transfer to the cold room, however, due to the very low volume of the tea in comparison to the room, the room will not heat up as significantly as the tea cools down. This is not a spontaneous process, and in order for this to occur, external work would have to be applied to the system. Clausius statement: heat cannot spontaneously flow from a material at a lower temperature to a material at a higher temperature. Kevin-planck statement: work can be converted completely to heat, but heat cannot be completely and continuously converted into work. What are some consequences of the second law: work requires organized motion. Heat is related to random collisions between atoms.
