Liquid
A Liquid is a fluid that can take the shape of a bottle if filled fully.
Solid
A solid is an object that takes up space.
Gas
A gas is a compilation of atoms that can’t be seen by the human eye.
Plasma
Plasma starts off as a gas and then becomes ionized from matter.
Energy
The time it takes to do something like work.
Thermal Energy
The energy of kinetic atoms.
Evaporation
When a substance changes from a liquid to a gas.
Sublimation
The time it takes for a solid to turn into a gas.
Condensation
When a substance changes from a gas to a liquid.
Crystalline Solid
A Crystalline Solid includes an arrangement of atoms and molecules.
Amorphous Solid
Amorphous Solids are atoms and molecules that aren’t in any particular order.
Surface Tension
An act of force being pushed upon a liquid to form liquid drops.
Kinetic energy
Kinetic means particles that are in motion.
Heat
Heat causes the temperature of a substance to change. Heating up an ice cube will turn it into a liquid.
Endothermic Change
When a solid changes into a liquid by melting it.
Exothermic Change
Exothermic means that changing a liquid to a solid will freeze the liquid in place.
Fluid
A state of matter where molecules are able to roam freely. This means their able to slide past each other and not locked in place.
Buoyant force
When an object is being pushed up and is able to float on water.
Pressure
Force being pushed against a certain amount of area.
Archimedes’ Principle
A principle that explains that an object’s fluid matches that of the volume of the fluid that it displaces.
Pascal
The SI unit of pressure.
Pascal’s Principle
A statement that states that the fluid in a vessel matches that of intensity and is able to go in every direction.
Viscosity
Where gas and liquid is resistant to flowing.
Bernoulli’s Principle
Where the speed of a fluid increases while the pressure decreases.
