What does dispersion mean in science terms?

dispersiveness is one of the three properties that all particles share: solid, liquid or gas. The other two properties are density and specific heat. The more a particle is dispersed, the lower its density and higher its specific heat. In the case of particles suspended in a gas, the heavier the particle, the greater the effect on the motion of the gas. The lighter the particle is, the less it will affect the behavior of the gas.

What does the word disperse mean in science?

This word is used to describe how particles break away from a larger mass. In simple terms, any object can disperse when it is held together by a force. For example, imagine a ball of clay: If you place a magnet over the ball, the magnetic force will hold it together. If you place an iron nail over the ball, the nail’s magnetic attraction will cause the ball to break apart.

What does dispersion mean in star terms?

Dispersions are one of the main characteristics of the chemical composition of a star. It includes two other properties of the star – its surface temperature and radius. The hotter a star is, the more its atmosphere is dispersed. Smaller stars have lower surface temperatures, which allows for a thicker atmosphere. This means the heavier elements are farther away from the star’s surface in these kinds of stars.

What does dispersal mean in science terms?

The term “dispersal” refers to movement away from a population’s center. Dispersal is important to ecosystems because it helps prevent the overexpansion of plant and animal species into areas that are already well-suited for them. For example, species that are widely dispersed can avoid competition with closely related species. Plant species that are vegetative and reproduce by growing new plants to fill available spaces can reproduce faster when they are widely distributed.

What do dispersion mean in astronomy terms?

Dispersions are extremely small variations in the measured positions of objects in the sky. The more precise a given telescope, the smaller the variations are likely to be. Dispersions are generally expressed in arc seconds or millimeters, and the smaller the unit, the better. Dispersions are very important for finding very small and extremely close objects. One example of an extremely close object might be an exoplanet that is orbiting very close to its star. An extremely small deviation in that object�
