States Of Matter Flashcards
solid
Something with a definite shape and volume; particles are in an orderly position,won’t move.
liquid
Change shape but not volume; particles are packed close together but slide over each other.
Gas
Have the freedom to move and spread in all different directions; particles are constantly moving and don’t stick together.
Plasma
When a gas becomes ionized
Energy
The ability to do work
Thermal energy
Kinetic energy of atoms in a substance
Evaporation
From a liquid to a gas
Sublimation
From a solid to a gas or from a gas to a solid
Condensation
A gas to a liquid
Crystalline solids
Atoms or molecules are in a orderly fashion.
Amorphous solids
Atoms or molecules are not in any kind of order
Surface tension
Force on particles of water that cause spherical shapes
Kinetic energy
Energy of motion
Heat
Temperature change
Endothermic change
Changes that require energy
Exothermic change
Energy being released as it is changing states
Fluid
Nonsolid state when the atoms or molecules are free to move around
Buoyant force
Upward force that happens when an object is immersed in or floating on a fluid
Pressure
Amount of force taken out every unit area of a surface
Archimedes’ principle
Buoyant force on an object in a fluid is a upward force that is equal to the volume of fluid that the object displaces
Pascal
SI unit of pressure; equal to the force of 1 N over an area of 1 M squared (abbreviation-Pa)
Pascal’s principle
A fluid in equilibrium that is in a vessel gets rid of a pressure that is equal in intensity in a directions
Viscosity
Not allowing a gas or liquid to flow
Boyle’s Law
Law that states that for a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure decreases as the volume decreases, the pressure increases
Charle’s Law
Law that states that for a fixed amount of gas at a constant pressure, the volume increases as the temperature increases and as the volume decreases the temperature decreases
Gay-Lussac’s Law
Law that states that the pressure of gas at a constant volume is directly the same to the absolute temperature
