Chapter 5 Supposed to be a Balloon =/. Balloon (red) ? P= must be 1 Atm ~0.5L ? T= 23ºC Gas: -Properties of gas are described by a) Volume b) Pressure c) Temperature (K) d) Moles -Characteristics of Gas a) VERY Compressible b) Can occupy less than 0.1% of its volume c) Forms homogeneous mixtures with other gases d) Flies like a “bullet” ~300 m/s -Gas Law a) Pressure- volume relationship (Boyle) Q.) Boyle. Increasing the pressure of the balloon from 1 atm to .100atm will decrease the volume from .5L to what? b) Pressure – Temperature relationship (Charles) Q.) Charles: Decreasing the temperature of the balloon from 25 ºC to -77 ºC decrease the volume from 0.5L to what volume? c) Volume-mole relationship (Avogadro) Q.) ? Mass of nitrogen (N 2 ) are contained in the balloon at STP (assume it is filled with N 2 *Do not leave too early (open book / Teamwork allowed.)

    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.
