Liquid
Substances that take shape of whatever it’s in and molecules are less packed then a molecule
Solid
The molecules are very tightly packed
Gas
Molecules are. Rey spread apart and aloud free movement
Plasma
A state of matter the becomes ionized after it becomes a gas
Energy
Amt. of work that can be done
Thermal energy
The Kinect energy
Evaporation
A change from liquid to gas
Sublimation
Solid changes directly into a gas without becoming a lquid also may be called for the reverse process
Condensation
Change from gas to liquid
Crystalline solid
A solid that has crystals
Amourphous solid
A solid which the particles have no order
Kinetic energy
Energy from a object in motion
Heat
Energy transferred from two different objects
Fluid
Atoms or molecules are free to move past each other like a gas or liquid
Buoyant force
The upward force on a floating object
Pressure
The amount of force applied per unit of a surface
Archimedes Principle
States that the upward force of a buoyant force is equal to the weight of its volume
Pascal
The si unit for pressure (Pa)
Pascals principle
States that a fluid in equilibrium contained in a vessel exerts a pressure of equal intensity In all directions
Viscosity
The resistance of the flow of a gas or liquid
Bernoullis principle
States that the pressure in a fluid decreases as the fluids velocity increases
