Q5. What is the change in enthalpy (in Btu/lb) of carbon dioxide gas if the change in internal energy is 100 Btu/lb?

2. The specific volume of water at (185 °C) and (100 %) quality is nearest: B. 0.174 m³/kg C. 0.145 m³/kg 0.001134 m³/kg D. 0.153 m³/kg

A piston-cylinder assembly contains a mystery substance that undergoes a series of processes. Process 1-->2: Constant pressure process at 5bar from v1=.07m3/kg to v2=.12m3/kg Process 2->3: Constant volume process to saturated vapor Process 3->4: Constant temperature process to quality of 50% Process 4->5: Constant volume process to 5bar Sketch the processes on Pt, Pv, and Tv, plots. Lable the axes including property values; use closed dots to show the states, use solid lines to connect the states, add number and arrows to make clear the states numbers and process directions. Could this be considered a thermodynamic cycle? Why or why not?

The pressure of a saturated vapor is a function of: 1. only quality 2. only specific volume 3. only temperature 4. temperature and specific volume
