Mix & Flow of Water Flashcards
Fluid
A substance with no fixed shape that is able to flow
Flow
A substance mustn’t form a pile when poured
Properties of fluids
Can flow
Have no fixed shape
Take shape of the container
Don’t form a pile when poured
Are liquids, gases, some gels and creams
Solid
Particles:
Close together with little space in between them
Vibrate
Have a definite shape and volume
Particles when heated turn into liquid
Liquid
Particles:
Vibrate and move around
Further apart than particles in a solid
Definite volume
No definite shape, take shape of the container
When heated turns into gas
Gas
Particles are vibrating and moving around
Farther apart than particles in a liquid
No definite volume or shape
Fill any container
Have the most energy of the three states
Particle model of matter
All matter is made up of tiny particles
Particles are always moving
Particles have spaces between them
Particles are attracted to each other
Each pure substance has a unique type of particle
Homogeneous
A substance looks like it’s made up of a single part
Heterogenous
A substance looks like it’s made up of more than one part
Pure substances
Contain only one type of matter
Can be elements or compounds
Elements
Purest substances you can get
Made up fo only one type of atom
Gold
Compound
Made up of 2 or more elements which are chemically combined
Very difficult to separate
Water
Mixtures
Material made up of two or more substances
Physically combined
Solutions
Completely dissolved
Homogenous
Can’t be separated by a filter
Salt water, tea, hot chocolate
Mechanical mixtures
Can be easily separated
Heterogenous
Fruit salad, chocolate chip cookies, sandwich
Solvent
A substance that dissolves absolute to form a solution
Solute
A substance that is dissolved in a solvent
Type of solvent
Some solutes are more soluble in certain solvents and less soluble in other solvents
Particle type
Some particles. will dissolve better than others due to shape and size
Temperature
Temperature of both solvent and solute affect the solubility
Dissolving rate
how quickly the solute will dissolve in a solvent
Motion in dissolving rate
Most solutes dissolved faster when stirred or shaken
Time in dissolving rate
Some substances will dissolve quickly some slowly
Size of solute particles in. dissolving rate
Smaller particles dissolve faster
Concentration
How much solute is found in a given amount of solvent
Dilute
A small amount of solute dissolved in the solvent
Concentrated
Large amount of solute dissolved in the solvent
Concentration
The actual amount of solute that is dissolved in the solvent
Saturated
The maximum amount of dissolved solutes possible
Solubility
The maximum amount of solutes that can be dissolved in the solvent
