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)
