CHEM 1B Lecture Notes - Lecture 2: Bouncy Ball, Elastic Collision, Ideal Gas
Document Summary
State under which conditions they are most ideal. Explain why these conditions lead to ideality. Many gases can be treated as ideal. Gas molecules do not interact with themselves or anything else. Gas molecules collide with themselves or the walls of the containers elastically. Elastic collision is one which all energy is conserved. Ex. when you have a perfect bouncy ball and you collided it with another perfect bouncy ball, they would bounce off each other and fly off with a total kinetic energy exactly equal to what they started with. But it doesn"t mean the gas as a bulk system doesn"t have a volume. In chem 1a, we talked about atomic radii, that gives us an approximate volume of each atom. An ideal gas does not have this volume; it has zero volume. Low pressure keeps volume of atoms negligible. Scenario: remember that ideal gasses do not really have volume.
