How liquid can be liquefied?
By adding pressure and reducing the temperature, gases can be liquified. 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 the difference between liquefied and liquid?
As adjectives the difference between liquefied and liquid is that liquefied is while liquid is flowing freely like water; fluid; not solid and not gaseous; composed of particles that move freely among each other on the slightest pressure.
Can be liquefied by?
Hence, both increasing pressure and decreasing temperature can help in liquefaction of gases. So, the correct option is option C. Note: Critical temperature is a temperature in which substance can be in liquid form only. After this temperature substance can be either in vapour form or gaseous form.
Can air be liquefied?
Air can be liquefied when renewable energy produced is greater than the grid demand; this allows energy to be stored in the form of liquid air instead of being wasted. Liquefaction of air can also be carried out when the energy demand from the grid is low, eg.
What is also known as liquefaction?
In physics and chemistry, the phase transitions from solid and gas to liquid (melting and condensation, respectively) may be referred to as liquefaction. The melting point (sometimes called liquefaction point) is the temperature and pressure at which a solid becomes a liquid.
What material is subject to liquefaction?
Poorly drained fine-grained soils such as sandy, silty, and gravelly soils are the most susceptible to liquefaction. Granular soils are made up of a mix of soil and pore spaces.
Is a fluid a liquid?
The fluid is the state of a specific substance, while the liquid is one of the states of matter. The basic characteristic of fluids is the flow of fluids. Liquids, on the other hand, flow and are described as having volume with no fixed shape. All liquids are fluids but not all fluids are liquids.
Is water a liquid or fluid?
Water is, by far, the most common liquid on Earth. The density of a liquid is usually close to that of a solid, and much higher than in a gas. Therefore, liquid and solid are both termed condensed matter. On the other hand, as liquids and gases share the ability to flow, they are both called fluids.
Can be best liquefied by?
A gas can be best liquefied by increasing the pressure and lowering the temperature.
Can be liquefied most suitably at?
Solution : For liquefaction of gas temperature should be lower than critical temperature. Also higher is the `P` in comparison to critical pressure easier is liquefaction .
Is water a fluid?
How can gas be liquified to a liquid state?
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 using the Joule-Thomson effect.
Is it possible to liquefy hydrogen into a liquid?
However, when it comes to the task of storing hydrogen for use, there is a hurdle to clear: Hydrogen exists as a gas by default but is most useful when stored as a liquid. Unfortunately, liquefying hydrogen isn’t as easy as turning steam into liquid water.
What kind of gases are used in liquefaction?
Two kinds of liquefied gases are widely used commercially for this reason, liquefied natural gas (LNG) and liquefied petroleum gas (LPG). LPG is a mixture of gases obtained from natural gas or petroleum that has been converted to the liquid state. The mixture is stored in strong containers that can withstand very high pressures.
How can a gas be liquefied under high pressure?
Cooling lowers the temperature of compressed gas and helps in liquefying it, Hence, a gas can be liquefied by applying high pressure and lowering the temperature (cooling). Was this answer helpful? Thank you. Your Feedback will Help us Serve you better.
