Lesson 6 Gas laws Gas laws are mathematical equations relating the volume to the number of moles, temperature and pressure of gases: V = f ( n , T , P ) The function f ( n , T , P ) is relatively simple for gases because intermolecular forces in gases are generally very weak Ideal gas law: PV = nRT The ideal gas law does not take into account gas type. Is this a reasonable hypothesis?

Lesson 6 Definition of pressure P = force / area Which force? Force resulting from the collision of the gas molecules against the walls of the container Which area? Area of the walls of the container holding the gas

    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.
