Mix And Flow Of Matter Unit Test 8 Flashcards
What is a slurry
A slurry is a mixture of water and a solid like dirt and water. Slurries can move solids in water
What are properties of fluids
Density buoyancy viscosity and compressibility
What is a fluid
A fluid is anything that has no fixed shape and can flow usually it is a liquid or a gas
What is a heterogeneous mixture
A mixture where the different substances can be seen
What is a homogenous mixture
A mixture where the different substances cannot be seen or a mixture that looks like it is all one substance
What is a suspension
A suspension is a cloudy mixture where the particles settle out, they are temporarily suspended ex, snow globe
What is a mechanical mixture
It is a heterogeneous mixture or a mixture where are the different substances are easy to see ex, salad
What are the different kinds of heterogeneous mixtures
Mechanical mixture, suspension
What is a colloid
A cloudy mixture where the droplets or tiny particles are too small to separate out. they are mixed together but not dissolved
Ex, paint
What is a solution
A very well mixed mixture or particles are small and dissolved ex, sea water
What are examples of homogeneous mixtures
Colloids, solutions
In a solution what are the solute and the solvent
The solute is the thing that is being dissolved in the solvent is the thing that the solute is dissolved into.
What is concentration
Concentration is the amount of solute dissolved into a specific amount of solvent (g/mL).
What is the difference between a concentrated and diluted solution
A solution that is very concentrated has a large amount of solute and small amount of solvent. Ex, pop. A diluted solution has a small amount of solute in a large amount of solvent. Ex, tap water
What is the difference between a saturated and unsaturated solution
An unsaturated solution is what a solution where more solute can dissolve that any given temperature. A saturated solution is a solution were no more solute can be dissolved at any temperature.
What is a supersaturated solution
A supersaturated solution is when there is more solute then the solvent can dissolve
What is solubility
The maximum amount of solute you can add at a certain temperature
What are factors that affect solubility
Temperature, type of solute, type of solvent
What are factors that affect the rate of dissolving (how fast something dissolves)
Temperature, the size of the particles (sugar cube vs powdered sugar), and agitation of the solvent (stirring it)
What is viscosity
How quickly a fluid can flow determined by a fluids internal friction that keeps it from flowing. A fluid with a high viscosity will have more internal friction and therefore it will flow slower. A fluid with a low viscosity will have less internal friction and will flow faster
What is flow rate
The flow rate of a fluid is how fast a fluid can flow. you can calculate flow rate by dividing the amount of fluid (mL) by how long it takes in seconds to flow down a ramp
How does temperature affect viscosity
As the temperature of a fluid increases it becomes less viscous and flows easier
How does the particle model of matter relate to temperature affecting viscosity
In the particle model of matter a liquid is made of particles that can slide and roll over each other they are spread apart and can move around a lot. When energy or heat is added to the liquid the particles slide and roll more quickly. As a result of this change the fluid flows faster and the viscosity will decrease
What is density
Density is the amount of matter (mass) in a given volume
