A colloid is a mixture in which one substance is divided into minute particles (called colloidal particles) and dispersed throughout a second substance. The mixture they form is called a colloidal dispersion. A colloidal dispersion consists of colloids in a dispersing medium. It doesn't have to be liquid.
A substance with particles too large to dissolve is called a suspension. In a suspension, the particles are visible and do not completely dissolve in the solvent, often settling out over time. Examples include sand in water or muddy water.

Will sand dissolve in boiling water?
No, sand will not dissolve in boiling water as it is insoluble in water. Sand is made of large particles of silicon dioxide which do not break down or dissolve in water at any temperature.
What are solids that do not dissolve called?
Solids that do not dissolve are called insoluble solids. These solids do not mix with a solvent to form a solution because their particles are too large or their bonds are too strong to break apart.
What is the ability so something to dissolve in water called?
The ability is hydrogen bonds, which form on the fly more easily than covalent or ionic bonds. Other chemicals that readily create hydrogen bonds are gases at room temperature, ammonia and hydrogen fluoride, or are unstable, hydrazine. Water is the only inorganic (not carbon based) liquid solvent that occurs naturally in large quantity. Hydrogen bonding also holds the double strands of DNA together.
Why does flour not dissolve?
Flour is a solid substance composed of starch and proteins. Unlike sugar or salt, which are soluble in water, flour does not dissolve because its particles are too large and do not break down easily in water. Flour forms a suspension when mixed with water, creating a thick paste instead of dissolving completely.
Is 1 mole of particles a very large number of particles or a very small number?
A mole of particles is a very large number, equivalent to 6.022 x 10^23 particles. This number is known as Avogadro's number and represents a mole of any substance, whether atoms, molecules, ions, or other particles.
How does an insoluble substance form a suspension?
When an insoluble substance is mixed with a liquid, the particles of the substance do not dissolve but instead remain suspended throughout the liquid. The suspension is formed when the particles are small enough to disperse in the liquid but large enough that they do not dissolve. The particles may settle over time due to gravity, requiring the suspension to be shaken or stirred to redisperse them.
What is the large amount of solute?
The "solute" is the substance you are trying to dissolve. The solvent is the substance you are trying to dissolve it in.

No, sand will not dissolve in boiling water as it is insoluble in water. Sand is made of large particles of silicon dioxide which do not break down or dissolve in water at any temperature.

What is mixture in which particles of one substance are large enough to settle out of another substance?
suspension
What are Mixtures in which particles of one substance are large enough to settle out of another substance?
suspension
What do you call the substance that settles out of a suspension?
The substance that settles out of a suspension is called a precipitate. This occurs when the particles in the suspension are large enough to no longer remain suspended in the liquid and settle to the bottom.
What is the ability so something to dissolve in water called?
The ability is hydrogen bonds, which form on the fly more easily than covalent or ionic bonds. Other chemicals that readily create hydrogen bonds are gases at room temperature, ammonia and hydrogen fluoride, or are unstable, hydrazine. Water is the only inorganic (not carbon based) liquid solvent that occurs naturally in large quantity. Hydrogen bonding also holds the double strands of DNA together.
Which will dissolve faster a substance with little surface area or the one with a large surface area?
A substance with a larger surface area will dissolve faster because it provides more contact points for the solvent to interact with, leading to a faster rate of dissolution compared to a substance with little surface area.

What is a mixture from which particles settle out upon standing called?
The mixture is called a suspension. In a suspension, the particles are larger and do not dissolve in the solvent, causing them to settle out over time.
