Determine the change in the entropy of air, in kj/kg-k, as it undergoes a change of state from 100 kpa and 20°c to 600 kpa and 300°c using the equation of state p(v-a) = rt where a = 0,02 m3/kg. also find the value using the ideal gas equation of state. use data from the tables. the value of the ideal gas constant for air is r= 0.287 kj/kg-k. the change in the entropy of air for the equation of state is kj/kg-k and for the ideal gas equation of state is kj/kg-k.
