Chapter 3- States of Matter Flashcards
Solid
Solids keep a definite shape and volume
Liquids
Take the shape of container. Definite volume, but not shape.
Gas
Atoms are widely spread. Doesn’t have a definite shape or volume.
Plasma
The fourth state of matter. Similar to gases, but different properties. Can be affected be electricity and magnetism.
Energy
Energy helps the states of matter change from one to another. Example, ice to water requires thermal energy.
Thermal energy
A heat energy, or kinetic energy.
Evaporation
When a liquid turns to a gas
Sublimation
When solids skip over liquid and turns to a gas
Condensation
When a gas changes into a liquid. The tiny droplets on the outside of a glass is condensation.
Crystalline solid
A certain order
Amorphous solid
Not in any particular order
Surface tension
The tension at the surface of liquid
Kinetic energy
The highest point, energy to move
Heat
When atoms move faster
Endothermic change
Melting point
Exothermic change
Freezing point
Fluid
The ability to flow because the atoms can past each other.
Buoyant force
A force that pushes upward
Pressure
Amount of force in a fluid
Achimedies Principle
The upward force on an object is equal to the weight displaced
Pascal’s Principle
A Change of pressure is transmitted to each part equally
Pascals
Is the unit of pressure
Viscosity
The resistance of flow in a liquid or gas
Charles’s law
Fixed amount of pressure at a constant temperature . If the volume of the gas decreases the temperature will increase.
Boyle’s law
Fixed amount of pressure at a constant temperature. The volume of a gas will increase as the pressure decreases. (P1)V1=(P2)V2
Gay-lassac’s law
The pressure of a gas increase with the temperature as long as the volume remains the same.
