Document Summary
Lecture 11 - ch 101 - heat and temperature, vapor pressure and bond polarity. There are three buckets of water, one cold water, one warm water, one mystery water. Person 1 dips their hand in the cold water and person 2 dips their hand in the warm water. Person 1 then dips their hand in the mystery water and says that it feels cold and person 2 does the same thing and says that it feels warm. The description of cold and warm is the description of heat which is the flow of energy. Person 1 felt cold because there was less thermal energy as the energy was being transferred to the water. Person 2 felt warm because thermal energy was being transferred to their hands. Thermal energy always travels from higher temperatures to lower temperatures. If q>0, it represents warm and if q<0 it represents cold. Thus, the relationship of q is directly proportional to change in t(temperature).
