What Is The Difference Between Solid Liquid And Gaseous State

This occurs as the molecules in the gas slow down and lose energy.

Molten lava is an example of solid rock which has liquefied as a result of intense heat. Gases may liquefy when they cool as is the case with water vapor. Consequently liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.

Solids have a definite shape to them. Liquids do not have a definite shape. Liquid state is a state or phase of matter that has stronger intermolecular forces between molecules than that of a gas and weak intermolecular forces than that of a solid whereas gaseous state is a state or phase of matter that has weak or no intermolecular forces between molecules than that of a liquid or a solid. Solid gas because of its free moving molecules.

Solid state lasers include all optically pumped lasers in which the gain medium is a solid at room temperature. Liquids can transform into another state e g. When a liquid is cooled down to its freezing point its molecules bond together to form a certain order becoming stronger and more rigid as it shifts to a solid state. Highly strong intermolecular forces between the molecules leads to a definite volume in solids.

Liquids exhibit short range order because strong intermolecular attractive forces cause the molecules to pack together. In this state the distinction between liquid and gas disappears. Gas refers to a state of matter do not have any shape but conform to the shape of the container completely in which it is put in. Solid refers to a form of matter which has structural rigidity and has a firm shape which cannot be changed easily.

This article however focuses on some of the more successful solid state liquid and gas laser designs. Liquid is a substance that flows freely having a definite volume but no permanent shape. On the other hand molecules in a liquid are closely packed but there is no regular pattern. A supercritical fluid scf is a gas whose temperature and pressure are above the critical temperature and critical pressure respectively.

Difference between solid liquid and gases. The intermolecular forces are practically non existent. Particles read molecules in a solid are densely packed in a regular pattern and they have very little space to have any kind of movement. Solids may liquefy when they heat up.

Densities of liquids are therefore more commonly measured in units of grams per cubic centimeter g cm 3 or grams per milliliter g ml than in grams per liter g l the unit commonly used for gases. A vapor can exist in equilibrium with a liquid or solid in which case the gas pressure equals the vapor pressure of the liquid or solid. The main difference between solid liquid and gas is that solid is a state of matter with tightly packed particles in a specific shape while liquid has loosely packed particles without any specific shape whereas gas has freely moving particles and covers the shape of the container in which it is enclosed. In general they can only vibrate and are not free to move from one place to another.

Thus there is no definite volume.
