What is a Fluid? |
Anything that has no fixed shape and can flow. Usually a liquid or a gas. |
|
|
What is a slurry? |
Is a mixture of water and solids where the solid is transported |
|
|
What is a pure substance? |
A pure substance is made up of one type of matter. All particles are the same |
|
|
What is a mixture? |
When two or more substances are combined together |
|
|
What is a Mechanical Mixture? |
You can see the different substances that make up the structure |
|
|
What is a solution? |
Looks like one substance |
|
|
What is a suspension? |
Cloudy mixture in which droplets or tiny pieces of one substance held within another substance |
|
|
What is a Colloid? |
A cloudy mixture with pieces so tiny that they don't separate quickly |
|
|
How do you make a solution? |
Dissolving one substance into another. |
|
|
What is a solute? |
A substance that dissolves in a solution |
|
|
What is a solvent? |
The substance that does the dissolving in a solution |
|
|
How does grinding up a solute affect the saturation of the substance? |
When you grind up the solute, it increases the surface area, which increases the empty spaces, and that ultimately lets the sugar particles move into the empty spaces. This increases the saturation rate. |
|
|
How does adding heat energy affect the saturation of the substance? |
Particles are moving faster, it is easier for the solute to find empty spaces. There are more empty spaces because particles have more energy and bump into each other pushing particles apart creating more empty space. |
|
|
Why does an object float in water? |
An object that floats on water has to have a lower density then water. Gravity will act on the object, and another force will act on water. Both forces act with particles. Gravity is trying to push the object down, while the other force on water is trying to do the exact opposite with water. Since water particles are stronger than the object's, the other force will overpower gravity and will not let the object be pushed down. That is why an object will float on water |
|
|
How do you find density? |
mass divided by volume |
|
|
What is "Natural Buoyancy?" |
When an object doesn't sink or float |
|
|
What do viscosity, density, and buoyancy have in common? |
They are all fluid properties |
|
|
What is viscosity? |
How quickly fluids flow. It is determined by a fluids internal resistance or friction that keeps it from flowing. The greater the friction or rubbing, the higher the viscosity. Fluids with high viscosity don't flow as easily as fluids with low viscosity. |
|
|
What is buyancy |
It is the ability of an object to float |
