Mix and Flow of Matter Unit Test Flashcards
(35 cards)
What are the properties of fluids?
- density
- buoyancy
- viscosity
- compressibility
What is a fluid?
Anything that has no fixed shape and can flow as a liquid an a gas
What is a heterogeneous mixture?
A mixture where all parts are can be seen
What is a homogeneous mixture?
A mixture where the different substances can’t be seen and the mixture looks like all one substance
What is a suspension?
A cloudy mixture where the particles eventually settle out but are temporarily suspended
What is mechanical mixture?
a heterogeneous mixture where all the different parts can easily be seen
What are the different kinds of hetero heterogeneous mixture’s?
- mechanical mixture
- suspension
What is a colloid?
A cloudy mixture where the particles are too small separate out they are mixed together but not dissolved
What is the solution?
A very well mixed mixture where the particles are dissolved
What are examples of homogeneous mixture’s?
- colloid
- solution
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 the dissolved into
What is concentration
The amount of solute dissolved in a certain amount of solvent
What is the difference between concentrated and diluted solution
A solution that is concentrated has a large amount of solute in a small amount of solvent a diluted solution has a small amount of solute solute and a large amount of solvent
What is the difference between a saturated and unsaturated solution
Unsaturated solution is a solution or more solute can be dissolve a saturated solution is were no more solute can be dissolved
What is a supersaturated solution?
Is where there is more solute than the solvent can dissolve
What is solubility?
The maximum amount of solute you can add add a certain temperature
What are the factors that affect solubility?
- temperature
- type of solute
- type of solvent
What are the factors that affect the rate of dissolving (how fast something dissolves)?
- Temperature
- The size of the particles( sugar cubes vs Powdered sugar)
- Agitation of the solvent( stirring it)
What is viscosity?
How quickly a fluid can flow based on the fluids internal friction that keeps it from Flowing *A fluid with a high viscosity will flow slower and a fluid with the low viscosity will flow faster
What is a flow rate?
How fast of fluid can slow you can calculate this by dividing the amount of fluid by how long it takes in seconds to flow
How does temperature affect viscosity?
As you increase the temperature the fluid it becomes less viscous and flows easier and faster
How does the particle model of matter relate to temperature affecting viscosity?
In the particle model matter liquid is made of particles that can slide past each other when energy or heat is added to the liquid the particle slide and roll more quickly as results of this change the fluid flows faster and viscosity will decrease
What is density?
Density is the amount of matter in a given volume
How do you calculate density?
Divide your mass by your volume
