Name: ____________________________ CHEG 2313 Thermo I Exam I Example 2 1. A gas is contained in a sealed, frictionless, piston-cylinder arrangement, where the piston mass and the atmospheric pressure above the piston remain constant. The gas is heated and expands in the cylinder. In this process: (4 pts) a. Work is done on the gas b. Work is done by the gas c. No work is done d. Insufficient information 2. Circle all of the variables below that can be directly measured: (6 pts) pressure volume internal energy length enthalpy time 3. In an adiabatic steady flow compressor, the magnitude of the shaft work done by the system (neglecting changes in kinetic and potential energy), is equal to: (2 pts) a. the change in enthalpy b. the change in internal energy c. none of the above d. not enough information 4. Air flows steadily and essentially at constant pressure through a pipe that is heated by a furnace, as shown in the diagram below. As the air flows through the pipe, does the mass flow rate: (2 pt)
