CHE K121 Lecture Notes - Lecture 1: Kinetic Energy, Heat Capacity
Document Summary
Lecture 1: states of matter, solid, particles are closely packed, usually in de nite arrangements, restricted to vibrational motion, rigid and incompressible, liquid, close contact, but free moving. Incompressible: gas, particles are far apart, constant rapid motion, frequently collide. Inde nite shape and volume: compressible, two factors a ecting the state of matter, attractive forces between particles, kinetic energy of the particles. Properties of matter: physical properties, can be observed or measured without changing the identity of the substance, chemical properties, can only be observed or measure by changing the identity of the substance. #1: do not depend on the amount of the substance, speci c heat is the amount of heat required to raise the temp of 1 gram of a substance by 1 degree celsius. Thursday, august 30, 2018: extensive properties, depends on the amount of the substance, heat capacity is the amount of heat that can be absorbed.
