If you drop a lump of sugar into a beaker of water the sugar particles will become evenly distributed throughout the water through what?

the lump of sugar will slowly dissolve and undergo osmosis, if you stir or swirl the beaker it this will happen much faster

Are there more particles in a beaker with a large amount of water in it or a beaker with a small amount of water in it?
There will be more particles in a pitcher with more water.
Why should a thermometer not touch the sides of the test tube and should be placed in the middle?
If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.
Description of osmosis?
osmosis means the movement of water from a high concentration gradient to a low concentration gradient, through a SEMI-permable membrane, osmosis is 'complete' whene both sides are in they state of equalibrium this means when the water molecules are evenly spread out. e.g. a potato clyinder in a water beaker, the water particles in the potato is greater than in the beaker of water, and so as the definition says '...from a high to low concentration...' the water molecules transferr from the potato to the beaker of water. If you don't get it ur dumb
What is the hypothesis of will food coloring spread faster throughout a beaker of cold water or hot water?
Pick a side and rephrase the question
To separate a mixtuer of copper sulfate and sand?
Get a funnel and a beaker and something to hold the funnel over the beaker. Put a paper which is fitted to the funnel so the sand cant get through, you pour the mixture of sand and copper sulfate into the funnel. So the sand stays on top of the paper and the liquids travel through the paper into the beaker.

There will be more particles in a pitcher with more water.
Why does diffusion eventually result in equilibrium?
I will use the sugar cube example. Equilibrium is established as a result of diffusion. For example, consider placing a sugar cube into a beaker of water. As the sugar cube dissolves, the sugar molecules diffuse throughout the beaker When the beaker is left undisturbed, the concentration of the sugar molecules will eventually remain the same throughout the beaker. Thus, equilibrium is established due to the same concentration of the sugar molecules throughout the beaker.
What will happen to dye crystals initially in the bottom of a beaker of water over a long period of time?
They will diffuse equally throughout the beaker
Why is the ink drop spread into the beaker of water?
The molecules in the drop of ink will diffuse through the entire beaker of water. This will result in a homogeneous solution because of diffusion. This will only happen if the ink is of similar density to water.
If a beaker contains glucose and is permeable to glucose what will happen to the glucose?
If a beaker containing glucose is permeable to glucose, then the glucose will go through the beaker.
Which is smaller a beaker or a test tube?
It depends on the volume of the beaker and the test tube. Although throughout my scientific experience, beakers are larger than test tubes.
Need a simple method to distinguish between a beaker containing a true solution and one containing a colloidal suspension?
To do this you use the most simple of tests. (The name of the test escapes me at the moment... it might be Light Scattering.) You simply shine a small light through the beaker, and if you have a colloidal suspension, the light should be visible through the colloid. If you should have a solution, however, the light will not appear through the substance. This is because the particles in the solution are far too small to scatter light, while the particles in the colloid are large enough to be able to scatter the light.
Why should a thermometer not touch the sides of the test tube and should be placed in the middle?
If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.
What do you observe To collect some moist soil from the field in a beaker and add water to it. After the soil particles have settled down observe a drop of water from the beaker under a microscope?
Some settlements of moss in rare cases and some tiny bacterial particles You can see the insects and microorganisms and bacteria too
The dispersal of ink in a beaker of water in an example of what type of diffusion?
The dispersal of ink in a beaker of water is an example of diffusion. The diffusion of water into or out of a cell is called osmosis.
In iron plus copper sulphate reaction do the contents stay the same throughout the reaction in the beaker?
it would be the same
If you place a paper clip below a beaker and pour water into the beaker why can't the paper clip be seen from the side of the beaker?
This is caused by the refraction of light as it moves through the water. When light passes through anything translucent or transparent, it bends. You have noticed the same thing when swimming.
