Changes of State
100
This pure substance cannot be separated into simpler substances by physical or chemical means
What is an element?
100
Mass per unit volume (aka: mass/volume)
What is density?
100
This state of matter has definite volume and shape, and it’s particles vibrate while locked in place
What is a solid?
100
These elements have properties of both metals and nonmetals
What is a metalloid?
100
In this change, particles gain energy and go from being very tightly packed and locked in place, to being able to slide past each other
What is melting?
200
A substance made up of atoms of two or more elements joined by chemical bonds
What is a compound?
200
A characteristic that can be observed without changing the matter’s identity
What is a physical property?
200
In this state of matter, the particles collide and slide past each other, but stay close together
What is a liquid?
200
These elements are shiny, and conduct heat and electricity
What are metals?
200
The change of a liquid to a vapor that occurs at the surface of a liquid
What is evaporation?
300
A combination of 2 or more substances that are NOT chemically combined
What is a mixture?
300
Reactivity and Flammability are examples of this type of property
What are chemical properties?
300
More than 99% of the matter in the universe is made up of this state of matter
What is plasma?
300
These elements are malleable and ductile
What are metals?
300
When particles lose energy and the attraction between them overcomes their motion and causes them to be closely locked in position
What is freezing?
400
All matter has these two characteristic properties
What are mass and volume?
400
Color change, production of a gas, or a change in temperature are all signs of a _________ change
What is a chemical change?
400
This state of matter has no definite volume or shape, and it’s particles collide randomly with one another
What is a gas?
400
These exist naturally in fixed ratios
What are chemical compounds?
400
When particles that are far apart lose energy and clump together as the attraction between them overcomes their motion and energy
What is condensation?
500
An easy method to determine the volume of an irregularly-shaped solid object
What is water displacement?
500
The ability of a substance to be pulled into wires
What is ductility?
500
This state of matter can be compressed
What is a gas?
500
The substance that dissolves in a solution
What is the solute?
500
In this change, particles gain energy and go from being very tightly packed to being spread far apart
What is sublimation?
