A) Work and Heat: 2?0?0 = 20 ; 20?070 20? 1) Describe and discuss with your group in your own words the definition is work and what is heat. 2) Looking at the two equations above, what are the intensive quantities (do not depend on the size of the system) does work and heat depend on? 3) Is volume an intensive or extensive quantity? What about entropy? Is the entropy of two systems combined the sum of the individual entropies? Is this consistent with the microscopic definition of entropy? 4) Explain why there is no minus sign in this equation for heat (unlike the equation for work). (Think in terms of microscopic definition of entropy.) 5) How would the equation for heat simplify if temperature was constant? 6) If you were to make a T-S (temperature vs. entropy) state diagram, what will the area under curve represent? (Recall P-V diagrams.) 7) How would you be able to determine the sign of heat from a T-S diagram
