How do scientists distinguish between the different types of colloids?
Scientists distinguish between different types of colloids based on the phase of the dispersed particles and the dispersion medium. Common types include sols (solid particles dispersed in liquid), foams (gas dispersed in liquid or solid), emulsions (liquid dispersed in liquid), and gels (liquid dispersed in solid). Analytical techniques like microscopy, scattering, and electrophoresis can help identify and characterize colloids.
What occurs when light is dispersed?
When light is dispersed, its different wavelengths travel in different directions because of their varying speeds in the dissipating medium. This results in the separation of colors, such as in a rainbow where sunlight is dispersed by raindrops into its constituent colors.
What is a measure of how much the energy of a particular system has become dispersed?
Entropy is a measure of how much the energy of a particular system has become dispersed. It is a measure of the number of ways a system can be arranged at a microscopic level.
Which does not let light pass through solutionmixturecolloidor suspension?
colloid is one of the three primary types of mixtures, with the other two being a solution and suspension. A colloid is a solution that has particles ranging between 1 and 1000 nanometers in diameter, yet are still able to remain evenly distributed throughout the solution. These are also known as colloidal dispersions because the substances remain dispersed and do not settle to the bottom of the container. In colloids, one substance is evenly dispersed in another. The substance being dispersed is referred to as being in the dispersed phase, while the substance in which it is dispersed is in the continuous phase.Properties of ColloidsIn order to be classified as a colloid, the substance in the dispersed phase must be larger than the size of a molecule but smaller than what can be seen with the naked eye. This can be more precisely quantified as one or more of the substance's dimensions must be between 1 and 1000 nanometers. If the dimensions are smaller than this the substance is considered a solution and if they are larger than the substance is a suspension. A common method of classifying colloids is based on the phase of the dispersed substance and what phase it is dispersed in. The types of colloids includes sol, emulsion, foam, and aerosol.Sol is a colloidal suspension with solid particles in a liquid.Emulsion is between two liquids.Foam is formed when many gas particles are trapped in a liquid or solid.Aerosol contains small particles of liquid or solid dispersed in a gas.When the dispersion medium is water, the colloidal system is often referred to as a hydrocolloid. The particles in the dispersed phase can take place in different phases depending on how much water is available. For example, Jello powder mixed in with water creates a hydrocolloid. A common use for hydrocolloids is in the creation of medical dressings.
Why is red light dispersed?
Red light is dispersed because it has a longer wavelength compared to other colors in the visible spectrum. This longer wavelength causes red light to be bent or scattered more as it travels through a medium, such as air or water, resulting in its dispersion.

How does a kapok tree reproduce?
when the kapok pops, its seeds go all over the place and then it will grow on a new kapok tree (i think =.=)
What lives with or on the kapok tree Does moss live on the kapok tree or do snakes live on the kapok tree?
Many different species live on or around the kapok tree. Moss could potentially grow on the bark of a kapok tree, especially in humid environments. Snakes may also inhabit kapok trees to seek shelter or prey on animals that visit the tree.
Are there any health hazards working with kapok fibers?
The health hazards that exist for working with Kapok fibers are only hazardous when the Kapok is burned. The fibers could be toxic. Kapok fibers are hypoallergenic and usually harmless.
When was The Great Kapok Tree created?
The Great Kapok Tree was created in 1990.

The relative molecular weight of kapok seed oil is 875.081.
How tall is a kapok tree?
A mature kapok tree may be 60 - 70 m.
