Phase Changes
The phase change from a solid to a liquid
Melting
Diameters of the basic particles of matter are traditionally measured in
Angstroms
State of matter that has a definite shape, definite volume and cannot be compressed. Particles are packed closely together and vibrate in a fixed position.
Solid
Cutting a piece of paper
Physical Change
Color of an object
Physical property
When enough heat is added to a liquid, what is the phase change from a liquid to gas
Boiling
The SI unit appropriate for measuring the size of atom sized particles
Nanometer
State of matter that has definite volume and cannot be compressed. Takes the shape of its container. Particle movement is random but particles stay close together.
Liquid
A car rusting
Chemical Change
The texture of an object
Physical Property
Condensation
The measure of molecular speed
Temperature
State of matter that has no definite shape or volume, can be compressed. Particles move at high speeds and are far from one another.
Gas
A pond freezing in winter
Physical Change
The corrosiveness of an object
Chemical Property
The change of a liquid to a gas at the surface of a liquid is called ...
Evaporation
Kelvin Scale
Forms at very low temperatures. Is the lowest energy state of matter.
Bose - Einstein Condensate
Cooking an egg
The tendency to rust
Chemical Property
Phase changes in a material are caused by...
Temperature changes
The theoretical point where all particle motion ceases and there is no energy
Absolute Zero
Forms at very high temperatures. Particles are moving at such high speed when they collide particles become electrified.
Plasma
Forming Sawdust
Physical Change
The density of an object
