document PDF (Teacher's Edition Only) Test your knowledge of gases Question 1 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 volume of Ar = 2 times the volume of He the volumes are equal Question 2 What are the conditions of STP? 1.00 atm and 0 degrees C 0 atm and 0 degrees C 1.00 atm and 25 degrees C 1.00 atm and 100 degrees C Question 3 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 4 According to Boyle's law, pressure and volume are inversely proportional have an inverse square relationship are directly proportional are not related Question 5 If the pressure on a gas doubles, and other factors remain the same, the volume will be reduced to one half unchanged doubled Question 6 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 insignificantly small about the same large Question 7 Which temperature scale(s) must be used in gas law calculations? Kelvin Kelvin or Fahrenheit Kelvin or Celsius Celsius Question 8 The atmosphere is approximately 20% oxygen and 80% nitrogen. If the atmospheric pressure is 1.0 atm, the partial pressure of oxygen is 1.20 atm 0.80 atm cannot be determined 0.20 atm Question 9 A gas behaves most like an ideal gas under conditions of low pressure and high temperature low pressure and low temperature high pressure and high temperature high pressure and low temperature Question 10 In the Ideal Gas Law PV=nRT, n represents number of moles radius ideal gas constant pressure Join eNotes to save your quiz results!
