San Francisco State University ENGR 303: Engineering Thermodynamics School of Engineering Prof. Ed Cheng, Spring 2011Homework 4 solutions NOTE: Solutions for HW problems that are based upon textbook problems reflect numerical values from the text. Numerical values may differ for these problems when they appear on iLearn. In such cases, the solution presented below provides the appropriate solution method. 1. The correct answer is (a). 2. The correct answer is (c). Comments about 1-2: Despite their confusing names, the specific heat at constant volume cvis always used to evaluate internal energy changes; the specific heat at constant pressure cpis always used to evaluate enthalpy changes. Neither one is limited to application in only constant-volume or constant-
