CHEM 1211 Lecture Notes - Lecture 4: Ideal Gas Law, Gas Constant, Kinetic Theory Of Gases
Document Summary
Chem 1211 chapter 5: **properties of gases**: gases have several unique properties, including low density, high compressibility, and the ability to expand and mix uniformly with other gases. Gas particles are in constant, random motion and experience very few intermolecular forces: **pressure**: pressure is the force exerted per unit area by gas particles as they collide with the walls of a container. Common units of pressure include atmospheres (atm), pascals (pa), and millimeters of mercury (mmhg or torr): **temperature**: temperature is a measure of the average kinetic energy of gas particles. In gas law calculations, it is essential to use the kelvin (k) temperature scale: **gas laws**: gas laws describe the relationships between the pressure, volume, temperature, and amount of a gas. **boyle"s law**: at constant temperature, the pressure of a gas is inversely proportional to its volume (p1v1 = p2v2). **charles"s law**: at constant pressure, the volume of a gas is directly proportional to its temperature (v1/t1 = v2/t2).
