CHEM 1314 Lecture Notes - Lecture 6: Partial Pressure, Molar Mass, Novella
Document Summary
Manometer: measures the pressure of the gas trapped in a container. Gaseous atoms or molecules exert forces when they collide with surfaces. The result of these collisions is pressure. Pressure is the force exerted per unit area by gas molecules as they strike the surfaces around them. Gas pressure is the result of the constant movement of the gas molecules and their collisions with the surfaces around them. Variation in pressure in earth"s atmosphere creates wind, which helps us predict weather. These laws describe the relationship between the 4 basic properties of gases pressure (p), volume (v), temperature (t), and amount in moles (n: these properties are interrelated when one changes, it affects the tohers. The pressure of a gas is inversely proportional to its volume. As p increases, v decreases by the same factor (p x v is constant) P1 x v1 = p2 x v2.
