Solids that are powdered-do they always go to the bottom of container?
Am83
No. Watch what happens with talcum powder. When the particles between the solid are more cohesive than the attraction to water molecules, they will not be "wetted" and remain floating.

Special properties of liquid?
A liquid is defined as something that has a constant volume but conforms to the shape of its container. This is different from a gas which has variable volume and conforms to the shape of its container. It is also different from a solid which has a constant volume and does not change to fit the shape of its container.
Are solids fluids?
No. A great illustration is glass. The only reason that we can see through glass is because it is a fluid; the proof being that when an eighty year old piece of glass is examined, flow can be detected because the glass sheet is thicker at the bottom.
Why are upwelling waters always cold?
they come from the colder waters on the bottom of the oceans
What is the difference between diffusion and dissolve?
Diffusion is the spread of particles from an area of higher concentration to an area of lower concentration. Diffusion can occur in gas or liquid.Dissolving occurs when one substance, the solvent, supports the particles of another substance, the solute, to form a solution. The two processes are similar.Example:Sugar in the bottom of a cup of coffee will slowly diffuse into the bottom of the cup dissolving as it goes. When we stir the coffee we make the process faster and the dissolving is uniform without a higher concentration at the bottom of the cup.Perfume or petrol (gasoline) in a container in the corner of the room will slowly diffuse out and we can smell it even when we are not next to the container. Again the concentration is higher the closer we are to the container.
How is the meniscus used in measuring the volume of liquids?
AnswerA meniscus is when the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. This causes the liquid to "stick" to the side of the container, creating a curve. The volume must be read at the bottom of the meniscus.
What device spins rapidly and causes the solids to settle to the bottom of a container?
Centrifuge
Reading the volume of liquid inside the graduated cylinder?
Always read from the bottom of the meniscus (where the liquid reaches up the side of the container).
What is meant by decantation?
Answer 1Until a Chemist can give a "chemistry" answer, I will use the answer from the perspective of wine making. Wine has many solids suspended in the raw fermentation batch. Over time, the solids will settle out to the bottom of the container.To get the "good" wine separated from the mess at the bottom of the container, tubing is inserted into the clear wine above, a syphon process is started.Then the pick-up end of the syphon is set just barely above the settled-out mess, so that only the clear wine is syphoned out, leaving the contaminated wine and solids in the original container.Therefore, the process of "decantation" is the removal of a "clean" portion of a liquid from above the sediment in a container.
Do liquids always fill their container?
Gravity. The gravitational pull of the Earth will exert a force on anything with a mass and pull it towards the centre of the Earth. As we're essentially standing on the surface of a sphere, the centre of the Earth is pretty much straight down and gravity will pull liquids to the bottom of any container.
How do you decant a solution?
Decanting can be used o separate a liquid from an insoluble solid. As the solid settles to the bottom of the container, the liquid can be carefully poured into another container leaving the solid (sediment) behind. Decanting can also be used to separate two immiscible liquids like oil and vinegar.
If the axis of rotation is near the top of the container will the denser particles tend to move to the top or bottom of the container?
Denser particles would move towards the bottom of the container due to centrifugal force.
What is the liquid in the bottom of your caterpillar container?
it is molting
When measuring you do the measurement from the bottom of the meniscus?
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.
The solid that is formed and usually sinks to the bottom of a soulution is the?
settable solids
How does the process of decantation work?
The process of decantation works by allowing solids to settle at the bottom of the mixture. This is a process that is used to separate mixtures.
How does the pressure at the bottom of a container depends on the container shape and the fluid height?
well here: DO YOUR HW ALONE
Why do streams deposit sediments?
It's the flow of water that carries solids, whenever the flow slows then some of the solids will fall to the bottom of the stream.
