What happens when particles are packed together?

What happens when particles are packed together?

Solids, liquids and gases are three states of matter. In solids, the particles are tightly packed together. In liquids, the particles have more movement, while in gases, they are spread out. The physical characteristics of those atoms and molecules decide its state.

What happens if molecules are close together?

the neighboring atoms or molecules are close together, making the solid not compressible and giving it a definite shape that is independent of the shape and size of its container.

What does it mean when particles are tightly packed?

solid
In a solid, particles are packed tightly together so they don’t move much. Solids also have a high density, meaning that the particles are tightly packed together. Liquids. In a liquid, the particles are more loosely packed than in a solid and are able to flow around each other, giving the liquid an indefinite shape.

In which state do the particles remain far apart?

In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little space between them. The particles in a liquid usually are still touching but there are some spaces between them. The gas particles have big distances between them.

What particles are packed close together?

Solids. A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume.

Why are particles close together in a solid?

Solid: Explain that in a solid, the particles are very attracted to each other so they are close together. The particles can move in their fixed positions but cannot slide past one another.

What is between particles that make up substances?

Intermolecular Forces. Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. The attractive intermolecular forces between particles that tend to draw the particles together.

What happens to pore volume when soil is compacted?

Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density.

How does soil compaction affect water infiltration and drainage?

Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a reduced rate of both water infiltration and drainage. This happens because large pores more effectively move water downward through the soil than smaller pores.

What causes soil to be compacted in a garden?

Compressing soil because of weight. Vehicles parked or driven over an area, construction activities and even places with a great deal of foot traffic can become compacted. It could be a riding mower’s tires running over an area repeatedly.

What happens if plants are planted too close together?

Nutrient Deficiencies. Overcrowded plants must compete with each other for soil nutrients, which can result in increased fertilizer needs. Soil contains a finite amount of nitrogen and other necessary plant nutrients. The more plants there are in a small space, the more quickly these nutrients are used up.
