Answer the following conceptrelated questions When analyzing

Answer the following concept-related questions: When analyzing the acceleration of gases as they flow through a nozzle, what would you choose as your system? What type of system is that? Is the state of the air in an isolated room completely specified by the temperature and pressure? Explain. The molar specific volume of a system V bar is defined as the ratio of the volume of the system to the number of moles of substance contained in the system. Is this an extensive or intensive property?

Solution

1.(a) The system is the volume of gases inside the nozzle. This is an open system, as mass can cross the boundary

(b) Yes, because temperature and pressure of air are two independent properties and and volume is constant

(c) Molar specific volume is an intensive property, as it is related to pressure and temperature
