document PDF (Teacher's Edition Only) Test your knowledge of gases Question 1 In the Ideal Gas Law PV=nRT, n represents radius pressure number of moles ideal gas constant Question 2 A gas behaves most like an ideal gas under conditions of low pressure and high temperature high pressure and low temperature high pressure and high temperature low pressure and low temperature Question 3 The atmosphere is approximately 20% oxygen and 80% nitrogen. If the atmospheric pressure is 1.0 atm, the partial pressure of oxygen is 0.20 atm 1.20 atm 0.80 atm cannot be determined Question 4 As a balloon rises into the atmosphere the atmospheric pressure decreases. What happens to the volume of the balloon? (assume no change in temperature) it increases it stays the same it decreases Question 5 Which temperature scale(s) must be used in gas law calculations? Kelvin or Celsius Kelvin Kelvin or Fahrenheit Celsius Question 6 According to Boyle's law, pressure and volume are directly proportional are inversely proportional are not related have an inverse square relationship Question 7 What are the conditions of STP? 1.00 atm and 25 degrees C 0 atm and 0 degrees C 1.00 atm and 100 degrees C 1.00 atm and 0 degrees C Question 8 How does the volume of 1.0 moles of He compare to the volume of 1.0 moles of Ar at the same temperature and pressure? cannot be determined from information given the volume of He = 2 times the volume of Ar the volumes are equal the volume of Ar = 2 times the volume of He Question 9 If the pressure on a gas doubles, and other factors remain the same, the volume will be unchanged doubled reduced to one half Question 10 According to the Kinetic Molecular Theory, when compared to the volume a sample of an ideal gas occupies the volume of the individual molecules is about the same insignificantly small large Join eNotes to save your quiz results!
