1 Gases assume the volume and shape of their containers. Gases have much lower densities than liquids and solids. Gases are the most compressible state of matter. Gases will mix evenly and completely when confined to the same container. 5.1 Physical Characteristics of Gases Sea level 1 atm 4 miles 0.5 atm 10 miles 0.2 atm 5.2 Barometer Pressure = Force Area ( force = mass x acceleration) 1 pascal (Pa) = 1 N/m 2 1 atm = 101,325 Pa 1 atm = 760 mmHg = 760 Torr 5.3 As P (h) increases V decreases Apparatus for Studying the Relationship Between Pressure and Volume of a Gas Add Hg Add Hg

2 P 1/ V P × V = constant P 1 × V 1 = P 2 × V 2 5.3 Boyle’s Law Constant temperature Constant amount of gas Example : A sample of Cl 2 gas occupies a volume of 946 mL at a pressure of 726 mmHg. What is the pressure of the gas (in mmHg) if the volume is reduced at constant temperature to 154 mL? P 1 × V 1 = P 2 × V 2 P 1 = 726 mmHg V 1 = 946 mL P 2 = 726 mmHg V 2 = 154 mL P 2 = P 1 × V 1 V 2 726 mmHg × 946 mL 154 mL = = 4460 mmHg 5.3 P × V = constant

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
