Problem
1. Are the mass and mole fractions for a mixture ever the same?
2. For a mixture, how many component concentrations are needed?
3. Are any of the properties (P, T, v) for oxygen and nitrogen in air the same?
4. If I want to heat a flow of a four-component mixture from 300 to 310 K at constant P, how many properties and which properties do I need to know to find the heat transfer?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
