What is liquefaction Byjus?

Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading. Liquefaction and related phenomena have been responsible for tremendous amounts of damage in historical earthquakes around the world.

What do you mean by liquefaction?

Liquefaction takes place when loosely packed, water-logged sediments at or near the ground surface lose their strength in response to strong ground shaking. Liquefaction occurring beneath buildings and other structures can cause major damage during earthquakes.

What is liquefaction of gas Class 9?

Liquefaction of gases is the physical conversion of a gas into a liquid state. When pressure on a gas is increased, its molecules closer together, and its temperature is reduced, which removes enough energy to make it change from the gaseous to the liquid state.

What is liquefaction in physics for Class 6?

Liquefaction- When solid is converted into liquid, it is known as liquefaction. Example of liquefication is- melting of ice.

What is liquefaction of gas Class 11?

The liquefaction of a gas takes place when the intermolecular forces of attraction become so high that they bind the gas molecules together to form the liquid state.

What is liquefaction?

WHAT IS A in liquefaction of gases?

Liquefaction of gases is the process by which substances in their gaseous state are converted to the liquid state. When pressure on a gas is increased, its molecules closer together, and its temperature is reduced, which removes enough energy to make it change from the gaseous to the liquid state.

What is liquefaction in chemistry example?

Examples. Gases are liquefied by condensation or cooling. Solids are liquefied by heating. Coal liquefaction yields liquid fuels.

What is liquefaction Wikipedia?

In materials science, liquefaction is a process that generates a liquid from a solid or a gas or that generates a non-liquid phase which behaves in accordance with fluid dynamics. It occurs both naturally and artificially.

What is liquefaction process in thermodynamics?

The process of refrigerating a gas to a temperature below its critical temperature so that liquid can be formed at some suitable pressure, also below the critical pressure.

What is liquefaction and solidification?

Liquefaction- When solid is converted into liquid, it is known as liquefaction. Example of liquefication is- melting of ice. Solidification- When a liquid is converted into solid, it is known as solidification.Example of solidification is- Freezing of water.

How do we liquefy the gases short answer?

By adding pressure and reducing the temperature, gases can be liquified The gaseous particles come together and begin to attract one another upon applying pressure.

How are gases liquefied Class 9?

The gases can be converted into liquids by bringing their particles closer so atmospheric gases can be liquefied either by decreasing temperature or by increasing pressure. Gas molecules can be squeezed together by one of two methods: by increasing the pressure on the gas or by lowering the temperature of the gas.

What is liquefaction of air in chemistry?

About Invention. Liquid air is air that has been cooled to very low temperatures (cryogenic temperatures), so that it has condensed into a pale blue mobile liquid. To protect it from room temperature, it must be kept in a vacuum insulated flask. Liquid air can absorb heat rapidly and revert to its gaseous state.

What is liquefaction A level geography?

Liquefaction is a particular hazard in areas where the ground consists of loose sediment such as sand, silt or gravel that is also waterlogged - often found in areas close to the sea or lakes. Intense earthquake shaking compacts the loose sediment together, forcing water between the sediment out and upwards.

Who invented liquefaction?

Pioneer work on the liquefaction of gases was carried out by the English scientist Michael Faraday (1791-1867) in the early 1820s.

What is the difference between condensation and liquefaction?

Liquefaction refers to the change of phase from a gas to a liquid. Condensation refers to the change of phase from a gas to either a liquid or a solid.

What is meant by liquefaction of soil?

Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading. Liquefaction and related phenomena have been responsible for tremendous amounts of damage in historical earthquakes around the world.

What is liquefaction starch?

2.1 Liquefaction. Liquefaction is the process of dispersion of the highly viscous gelatinized starch granules (∼35% w/v) and their partial enzymatic hydrolysis. Thermostable amylases are employed in this step as the process occurs at higher temperature.

What is its importance in liquefaction of gases?

Ans: The importance of liquefaction of gas is that they can be stored and transported in a much more compact form than done in the gaseous state. For example, the two most important gases are LPG and Liquid Oxygen. Q. 6.

Which is method of liquefaction of gases?

In general, gases can be liquefied by one of three general methods: (1) by compressing the gas at temperatures less than its critical temperature; (2) by making the gas do some kind of work against an external force, causing the gas to lose energy and change to the liquid state; and (3) by making gas do work against ...

How is ammonia gas liquefied?

By applying high pressure and lowering the temperature the ammonia gas can be liquified. When a high pressure is applied to ammonia gas, it gets compressed (into a small volume), and when we also lower its temperature, it gets liquefied.
