What is the Definition of a Solid?
*Definite shape and volume
*PE of bonds limit particle motion
*Particles vibrate in relatively fixed positions
What is the Definition of a liquid?
*Definite Volume
*Takes shape of the container
*PE Of the bonds is lower than in solids
*Particles have more KE than in a solid state
What are the States of matter?
*The nature of the bonds betweed the particles(PE)
*The motion of the particles(KE)
What is the Definition of Gases?
*No Definite shape and volume
*takes shape of container
*PE between particles is zero
*Greater KE than in solid and liquid states
What is Endothermic?
Endothermic Some phas changes require heat to be added to matter
What is Exothermic?
*Some changes require heat to be removes from the matter
What are Phase Changes?
*Melting Point-matter exists in both solids and liquid states
-if matter is held at the melting point and equilibrium will occur
*Boiling Point-Matter exists in both liquid and vapor states
-if matter is held at the boiling point equilibrium will occur
What is a triple point and a critical point?
*Triple Point-point on the grah where all 3 phases of matter can co exist(be together)
*Critical Point-point on the graph where theres a phase boundry when you get past that point there is no longer a boundry between the three
What is the difference of Heterogenous compared to Homogenous?
*Heter-Soil,dirt,rocks,mineras,plant food, decomposed animals and plants
*Homo-Milk,water,fat,sugar
What is a Solute?
The thing that is being dissolved
What is a solvent?
Medium that is being dissolved
*Water
What is a Soultion?
Homoegeneous mixture of two or more substances in a single phase
What is an Alloys?
Soultions of solids
-brass(copper;Zinc)
-Sterling(Silver;Copper)
What is an Electrolyte?
It is a Solution that conducts an electrial current
*Non Electrolyte-does not conduct electric current ex:sugar(no ions)
Solute
Medium that is being dissolved ex:(salt,sugar,&Kool Aid)
