Why is hand cream a colloid?
Hand creams are often colloids because they contain small particles of oil or wax dispersed within water. These particles are too small to settle to the bottom of the cream, creating a stable emulsion. This gives the hand cream its smooth and creamy texture.
How can different sized particles can be removed from water?
Different-sized particles can be removed from water using physical methods such as filtration, sedimentation, or centrifugation. Filtration involves passing water through a barrier that traps particles based on size. Sedimentation allows larger particles to settle at the bottom of a container, while smaller particles remain suspended. Centrifugation uses centrifugal force to separate particles based on size and density.
Is salt water a colloid suspension or solution?
Salt water is a solution, not a colloid suspension. In a solution, the solute particles are dissolved on a molecular level and do not settle out. Colloid suspensions, on the other hand, have larger solute particles that do not dissolve and may eventually settle out.
What is the difference between condensate and water?
Unless any extra particles/sediments collected on the water particles(gas), they do not differ. Condensate is just when water particles(gas), have collected on an object after evaporation, and this process runs all on water. One example is when after you take a shower, the steam, (water particles/gas), collects on a mirror and drizzles down the mirror. This ends up being water!!!
What happens when you boil water too long?
Boiling water too long can result in the water evaporating completely, leaving behind minerals and impurities in the pot. Over-boiling can also lead to a more concentrated solution of minerals in the water, potentially changing the taste or quality of the water.
Does steam or water have the greatest distance between particles?
Steam has a greater distance between particles compared to water because steam is in a gaseous state where the particles have more space between them and move more freely. Water, on the other hand, is a liquid with particles that are more closely packed together.
When holding a cold drink on a warm summer day your hand becomes colder and the drink becomes warmer why?
This happens because thre are particles in your hand and particles in the drink. The pareticles in your hand are hot, and in the drink, cool. When the particles are mixed, they find a medium temperature. So as both objects are adjusting to this new middle ground in the temperature you notice the difference. (they both become the same temp.) ' You can prove this by getting a cup of steaming hot water, and a cup of freezing cold water, pour both into a large bowl and mix it, after its mixed, put your hand in, it won't be hot or cold, but luke warm (or about there, depending on how hot or cold the water you used was). Hope this helped :)
Why is hand cream a colloid?
Hand creams are often colloids because they contain small particles of oil or wax dispersed within water. These particles are too small to settle to the bottom of the cream, creating a stable emulsion. This gives the hand cream its smooth and creamy texture.
Does clay soils have a coarse texture?
No, clay soils have a fine texture with very small particles that have a high water-holding capacity. Coarse soils, on the other hand, have larger particles and drain water more quickly.
What happens to the tens digit when you go past 100?
Nothing happens to it. It stays right where it is on the right hand side of the whole number.

What happens to arthurs sword when sir bedivere finally throws it into the water?
finally trows it in the water and then there came an arm and hand above the water which caught it and shook and brandished it thrice and then vanished with the sword into the water.
Is sound energy formed by the movement of electrically charged particles?
No, sound energy is produced by the vibration of particles in a medium (such as air, water, or solids). When an object vibrates, it creates movement in the particles of the medium, which then travel as waves. Electrically charged particles, on the other hand, create electromagnetic waves, such as light.
What is a mixture in which some of the particles will settle out?
Mixtures in which some of the particles settle out are called suspensions. An example of a mixture is dirt mixed with a large amount of water. On the other hand, mixtures in which the particles do not settle out are called colloids.
Does sand or dirt soak up water better?
Sand tends to soak up water better than dirt because sand particles are larger and more porous, allowing water to flow through and be absorbed more effectively. Dirt, on the other hand, may have more compacted particles that can hinder water absorption.
How do you pull agood prank on sleeping boys?
put there hand in warm water while they sleep! you'll have to try it to see what happens. or shaving gel on there hand and itch there nose.
Does water flow faster through soil or gravel?
Water typically flows faster through gravel compared to soil. This is because gravel has larger pore spaces between particles, allowing water to move more freely. Soil, on the other hand, has smaller pores and more fine particles that can slow down the flow of water.
