Revision Flashcards
properties of a solid?
Solid has a fixed shape and a fixed volume, Solid cannot be compressed, Solids have a high density,
Particles in a solids are tightly packed together
properties of a liquid?
It has fixed volume but not fix shape and size, Liquids are more compressible, Particles in a liquid are close together but can slide past each other.
properties of gas?
It has no fixed size, shape, or volume and particles are far apart so they move freely.

Solidification
what is boiling point?
the temperature at which its vapor pressure is equal to the pressure of the gas above it.
what is melting point?
the temperature at which a given solid will melt
what is the definition of matter?
anything with both mass and volume
what is the definition of solute?
a substance that dissolves in a solution
what is the definition of solvent?
a substance that (mostly liquid) which is capable of dissolving a substance creating a solution
what is the definition of soluble?
capable of being dissolved in a liquid
what is the definition of solubility?
a substances that dissolves in another subtance
what is the definition of solution?
the result of a solute dissolved in a solvent
what is the definition of suspension?
when a solid is mixed with a liquid but the solid doesn’t dissolve in the liquid. There is no solute or solvent as nothing dissolves.
what is the definition of evaporation?
the process of turning from liquid into vapor
what is the definition of filtration?
filtering a solid and a liquid
what is the definition of decanting?
separation of liquid from solid
what is the definition of distillation?
a process of changing a liquid into vapor
what is the definition of chromatography?
a process for separating components of a mixture
what is the definition of sieving?
a separation technique based on the difference in particle size.
centrifuging definition?
Centrifuges can be used to separate mixtures, by spinning them at very high speeds.
