Question: Consider the following table of measurements of pressure vs. volume for air in a closed volume at room temperature,
Pressure Volume
(kPa) (cm3)
90.9 24.89
73.6 30.73
59.5 37.93
a. Show that these data obey Boyle's law.
b. How many molecules are there in this volume? Show how you got your answer.
c. What is the rms velocity of the oxygen molecules in this sample of air? Explain how you got your answer.
d. If the temperature is increased by 15%, by how much does the rms velocity of the oxygen molecules change? Explain.
