Science Intro to Matter Quiz Flashcards
liquid to gas
Vaporization
Properties of
Solids
have a definite shape and a definite volume
properties of plasma
99.9 percent of matter in the universe is made of plasma
has an indefinite shape and an indefinite volume.
plasma has an electrical charge.
Most of the plasma in the universe is found within stars.
solid to gas
Sublimation
The particle theory
1 all matter is made of tiny particles
2 particles have empty spaces between them
3 particles are moving randomly all the time
4 particles move faster and spread farther
apart when they are heated
5 particles attract each other
plasma to gas
Ionization
Pure substance
Matter that contains only one kind of particle
All parts of the substance are the same throughout and have the same properties.
gas to liquid
Condensation
Compound
Contains particles that is a mix of two or more different elements
Homogeneous
a mixture that looks like pure substance; a uniform mixture of two or more substances
Recombination
gas to plasma
Heterogeneous
a mixture with different parts that you can see
Solutions
Solutions are made up of two or more substances, but have the same appearance.
Solubility
the ability of solute to dissolve and form a solution when added to a solvent.
Soluble vs. Insoluble
Soluble: the solute is capable of dissolving in a certain solvent
Insoluble: the solute isn’t able to dissolve certain solvent
Classifying solutions
Qualitative
Concentrated : contains a large amount of solute and very little solvent.
Dilute: has very little solute dissolved into the solvent
Quantitative
the exact amount of solute dissolved into a solvent
Saturation
All solutions have a maximum amount of solute that will dissolve into a given amount of solvent at a given temperature.
Unsaturated vs. Saturated vs. Supersaturated
A saturated solution is one that has been formed using the maximum amount of solute that will dissolve into a solvent, without adding more solvent or changing the temperature of the solvent.
A saturated solution can be cooled to a temperature where it forms a supersaturated solution, which contains more solute than would normally dissolve in the solution.
Solubility and the Particle Theory
Particles have forces of attraction between them, and that they are in constant motion.
This means that in a solution, solute particles are bumping against other solute particles and solvent particles as well.
