SHORT ANSWER PROBLEMS (Points vary 4. The density of air increases as it flows through a tube. The volumetric flow rate of air at the outlet is the volumetric flow rate at the inlet. (2 pts) A. equal to B. greater than C. less than Explain your answer (2 pts): /4 5. Consider two vapor mixtures of saturated water in air. One is at 20°C and 1 atm and the other is at 40°C and 1 atm. Which one has a higher partial pressure of water, Pw? A. 20 °C and 1 atm B. 40 °C and 1 atm C. pw is the same in both mixtures D. impossible to know Explain your answer (2 pts): 14 6. Draw an arrow on the diagram below to explain what happens when a piston cylinder initially full of a vapor at point C is compressed at a constant temperature. (3 pts) Is there a phase change? (1 pt) Explain your reasoning (2 pts): Temperature

Explanation / Answer

Ans 4 : C) less than

The density of air increases as it flows through a tube . The volumetric flow rate of air at the outlet is less than the volumetric flow rate at the inlet.

The flow rate is inversely proportional to the density of the substance. So more the density , less is the flow rate. Then the flow rate at outlet will be lesser than the inlet.
