Sublimation. Most substances go through the logical progression from solid to liquid to gas as they’re heated — or vice versa as they’re cooled. But a few substances go directly from the solid to the gaseous state without ever becoming a liquid. Scientists call this process sublimation.

Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

This is because the particles are tightly packed in both states. The same number of particles in a gas spread further apart than in the liquid or solid states. The same mass takes up a bigger volume . This means the gas is less dense.

The kinetic molecular theory of matter states that: The average amount of empty space between molecules gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases. There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together.

The main difference is that in a gas, the atoms remain intact and generally linked into molecules, but in plasma, at least part of the electrons have completely separated from their atoms. In other words, plasma particles are charged, whereas gas particles are largely uncharged.

When LPG (Liquefied Petroleum Gas) is used for household purposes, it is measured in mass, in kilograms. LPG is weighed in gas cylinders/bottles, and the cost is based on its weight. During transportation, LPG is put under pressure and measured in large quantities, in tons (i.e. 1000 kg).

Solids are marked by their definite shape and volume. On the other hand, the particles in solids are present very close to each other and the intermolecular gaps are very less. The intermolecular forces are thus high giving them making them rigid and dense. Thus, solids are denser than liquids and gases.

In general, solids are denser than liquids, which are denser than gases. . The gas particles have big distances between them. Solid In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy.

The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure. With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly.

A solid is matter that has a fixed volume and a fixed shape. A liquid is matter that has a fixed volume but not a fixed shape. A gas is matter that has neither a fixed volume nor a fixed shape. Like a gas, plasma lacks a fixed volume and shape.
