Homework #6 Due: October 12, 2005 (Wednesday) 1. The volume of a gas under normal conditions is observed to be _________ proportional to the temperature and ___________ proportional to the pressure. Your answer should be either directly or inversely in either case and should be entered as two words separated by a comma and a space in Blackboard. 2. A plot of pressure versus inverse volume (1/V) at constant temperature (isothermal = same temperature) is… a) a straight line with a positive slope at 45 o . b) a straight line with a negative slope. c) a straight line with a positive slope going through the point (0,0). d) a hyperbolic curve e) a logarithmic curve. 3. True or False . A plot of pressure versus temperature for a given number of moles of gas at a given volume (isochoric = same volume) gives exactly the same for all gases (assume ideal gas behavior). 4. A plot of volume versus 1/T for a given number of moles of gas at constant pressure (isobaric = same pressure) is a) a logarithmic curve. b) a straight line with a negative slope. d) a straight line with a positive slope going through the point (0,0). d) a hyperbolic curve e) none of these. 5. Convert 54.2 kPa into torr. a) 305 torr b) 232 torr c) 407 torr d) 760 torr e) 229 torr f) None of these. 6. At the peak of Mt. Everest, the pressure is approximately 270 mm Hg. Determine the pressure in atmospheres at that height. a)
