the temperature at which a solid begins to liquefy
What is melting point?
100
What is one characteristic of a gas?
Indefinite shape.
100
What is a characteristic of a solid?
Specific shape, definite volume, or high density.
100
What type of shape does a liquid have?
Indefinite shape
100
What happens in thermal expansion?
Substances increase in size
200
The movement of particles from areas of high concentration to areas of low concentration.
What is diffusion?
200
Gases have what kind of density?
Low density
200
a solid that has some liquid properties... i.e. glass and plastic
What is and amorphous solid?
200
What type of volume does a liquid have?
Definite volume.
200
Found in the sun, lightning, neon, and fluorescent tubes
What is plasma?
300
The ability of a fluid to exert a upward force on an object in it.
What is buoyancy?
300
What happens when a gas is cooled?
It shrinks
300
What type of density does a solid have?
High density.
300
What type of density does a liquid have?
High density.
300
The principle that states as the velocity of fluid increases, the pressure exerted by the fluid decreases.
What is Bernoulli's Principle?
400
The force exerted per unit area.
What is pressure?
400
What is one way to measure a gas?
Either temperature, volume, or pressure
400
The amount of energy needed to change a substance from a solid to a liquid.
What is heat of fusion
400
What happens to an object if its density is less than the density of the fluid it is placed in?
The object will float.

This principle relates volume and temperature. It states that at a constant pressure: as temperature increases, volume increases. At a constant pressure: as temperature decreases, volume decreases.
What is Charles law?
500
What is a liquids resistance to flow?
What is viscosity?
500
What happens when a gas is heated?
It expands
500
What is a liquid crystal?
A small crystal in solids that does not lose its shape when everything else around it melts.
500
What is the most common liquid on Earth?
Water
500
What law states that as volume decreases pressure increases and as pressure decreases volume increases.
