The physical process where matter moves from one state to another.
Example: Evaporation and solidifications are changes of states.
pt_br: Mudança de estado.
Concentration
Noun
The relative amount of a given substance contained within a solution or in a particular volume of space.
Example: The high concentration of substances like sugar in substances like water, may change its density.
pt_br: Concentração
Density
Noun
Degree of consistency measured by the quantity of mass per unit volume.
Example: If you add sugar to water, its density may raise.
pt_br: Densidade
Evaporation
Noun
The process of turning a liquid to vapor.
Example: After the precipitation, the water of rain pass through the process of evaporation.
pt_br: Evaporação
Flow
Noun
The action or fact of moving along in a steady, continuous stream.
Example: The flow of water into the pond.
pt_br: Fluxo
Flow rate
Noun
Is the mean speed that a fluid takes to move from one point to another.
Example: The kids did the experiment right, but they forgot to measure the flow rate.
pt_br: Quociente de vazão.
Fluid.
Noun.
A substance that has no fixed shape and yields easily to external pressure; a gas or (especially) a liquid.
Example: Water and juices are fluids.
pt_br: Fluido.
Liquid
Noun
It's a fluid that flows freely but is of constant volume.
Example: Water is liquid.
pt_br: Líquido.
Matter
Noun
Physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
Example: "the structure and properties of matter"
pt_br: Matéria
Particle
Noun
A minute portion of matter.
Example: Tiny particles of dust
pt_br: Partícula
Pressure
Noun
Continuous physical force exerted on or against an object by something in contact with it.
Example: The size of the space influences the flow of water, because of the pressure.
pt_br: Pressão
Solid
Adjective.
Not liquid or fluid, it is firm.
Example: The table is solid.
pt_br: Sólido
Solidification
Is a phase change of matter that results in the production of a solid.
Example: Ice is the solidification of water
pt_br: Solidificação
Temperature
Noun
The degree or intensity of heat or of cold in a living organism or in a non-living organism
Example: "Her temperature is hot!"
pt_br: Temperatura
Viscosity
Adjective.
The state of being thick, sticky, and semi fluid in consistency, due to internal friction.
Example: Sometimes, adding sugar to liquids raises its viscosity.
