How are gases liquefied Class 9?
When enough pressure is applied, the gases are highly compressed into a small volume. The particles of gases get so close together that they start attracting one another sufficiently to form a liquid. Therefore, Gases can be liquefied by applying high pressure and low temperature.
How can gases be liquefied short answer?
Answer : Gases can be liquefied by applying pressure and lowering temperature. When a high pressure is applied to a gas, it gets compressed (into a small volume), and when we also lower its temperature, it gets liquefied. So, we can say that gases can be liquefied (turned into liquids) by compression and cooling.
Which gas can be easily liquefied?
The permanent gases have weak intermolecular forces of interaction which makes the process of liquefaction impossible to carry out. Since the options have hydrogen, oxygen and nitrogen, it is clear that they are permanent gases. Only chlorine can be liquified easily by applying the suitable pressure on it.
Is used for liquifying of gas?
The gas stream is typically separated into the Liquefied Petroleum fractions (butane and propane), which can be stored in liquid form at relatively low pressure, and the lighter ethane and methane fractions. These lighter fractions of methane and ethane are then liquefied to make up the bulk of LNG that is shipped.
Which gas is called dry?
Dry gas, natural gas that consists of little more than methane, producing little condensable heavier hydrocarbon compounds such as propane and butane when brought to the surface. In the United States, dry gases are defined as those that contain less than 0.1 gallon of condensables per 1,000 cubic feet of produced gas.
Which gas is known as dry?
Dry Gas is a common name of carbon dioxide in solid.
What is sublimation and give an example?
Sublimation, in physics, conversion of a substance from the solid to the gaseous state without its becoming liquid. An example is the vaporization of frozen carbon dioxide (dry ice) at ordinary atmospheric pressure and temperature. The phenomenon is the result of vapour pressure and temperature relationships.
Why a gas can be liquefied easily?
In case of liquids, the space between particles is less and so is the kinetic energy of the particles in liquid. So, we can liquefy a gas into liquid if we decrease space between them and also decrease their kinetic energy. Note: Critical temperature is a temperature in which substance can be in liquid form only.
Which gas Cannot be liquefied?
An ideal gas cannot be liquefied because there is no intermolecular force of attraction between the ideal gas molecules. (A) Ideal gas molecules are separated from each other by large space and the actual volume of the gas molecule is negligible with respect to the volume of gas.
What happens to natural gas when it is liquefied?
When natural gas is liquefied, it shrinks more than 600 times in volume. LNG is mostly methane plus a few percent ethane, even less propane and butane, and trace amounts of nitrogen. When liquefied, natural gas that would fill a beach ball… …becomes LNG that can fit inside a ping-pong ball.
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 does a gas change from gaseous to liquid?
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.
How big is the volume of natural gas when it becomes a liquid?
LNG is natural gas that is cooled to -260° Fahrenheit, the temperature at which natural gas becomes a liquid. The volume of the liquid is 600 times smaller than the gaseous form.
