Unformatted text preview: Department of Chemical Engineering ChE 110A University of California, Santa Barbara Winter 2010 Problem Set No. 4 Due: Wednesday, January 27, 2010 Objective : To use the First Law and the concepts of enthalpy and heat capacity to assess processes in open and closed systems. Note: Numerical values for some problems have been changed from those in the book. Problem 13 (thought problem) Experiments on an unknown gas show that its heat capacity is well-described by the following expression: g G / where is a unitless constant and a constant with units of inverse temperature. Indicate whether each of the following statements is true or false. If false, explain why. (a) The gas cannot be considered an ideal gas. (b) Upon isochoric heating from to , the change in internal energy is given by . (c) Upon adiabatic compression to one-third its original volume, the temperature change of this gas can be found using 3 ....
