Mix and Flow of Matter Flashcards
Matter
Matter is anything that has volume and mass.
Agitation
Agitation is one way of making a solute dissolve faster.
Particle Model
By using the particle model, you can explain why liquids and gases flow but solids do not.
Fractional Distillation
The process that yields different petroleum products is known as fractional distillation.
Viscosity
The property that describes
a liquid’s thickness or thinness is
called viscosity.
Suspension
A heterogeneous mixture in which the particles settle slowly
after mixing is a suspension.
Buoyancy
Buoyancy is the tendency for materials to rise or float in a fluid.
Colloid
A heterogeneous mixture in which the particles do not settle is a colloid.
Density
Density can be described as the
“crowdedness” of the particles that make up matter. In scientific terms,
density is mass per unit volume of a substance.
Saturation
Saturation means holding as much moisture as possible
Solute
The solute is the substance that dissolves in a solvent to form a solution.
Solubility
The limit to how concentrated a solution can become is called solubility.
Solvent
When sugar dissolves in water, we call the water the solvent and the sugar the solute.
Desalination
Desalination means
removing the salt from salty water.
Hydraulic Systems
Devices that transmit
applied forces through a liquid to move something else, because of pressure, are called hydraulic systems.
Homogeneous mixture
A Homogeneous mixture of substances in which no settling occurs is a solution.
Pneumatic Systems
Pneumatic systems are similar to hydraulic systems, except gases are used instead of liquids.
Heterogeneous Mixture
Mixtures that contain two or more materials that are still visible are called heterogeneous mixtures.
Melting
All solids can become liquids
through the process of melting.
Evaporation
Evaporation is a slower form of vaporization that occurs over a wide range of temperatures.
Mechanical Mixture
Mixtures that are obviously heterogeneous are usually called mechanical mixtures.
Condensation
The change from gas to liquid is called condensation.
Sublimation
Sublimation is an unusual change of state that occurs when either a solid turns into its gaseous state or a gas turns into a solid without becoming a liquid first.
Filtration
The process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles.
Pressure
Pressure is defined as the physical force exerted on an object.
