How do we liquefy the gases very short answer Class 9?
We can liquify gases by applying high pressure and reducing the temperature.
What are the two ways of liquefy gases?
The two ways to liquefy the gases are applying pressure and reduce the temperature. Explanation: The gases can be changed to liquid by applying pressure as due to pressure the particles get closer and they change to liquid.
Is it possible to liquefy atmospheric gases If yes suggest a method Class 9?
Yes it is possible to liquify atmospheric gases. Gases can be liquefied by applying high pressure and low temperature. …
What is Dry Ice suggest a method to liquefy a gas?
Unlike regular ice, dry ice doesn’t melt into a liquid as it warms up. Instead, it converts directly back into its gaseous form in a process known as sublimation.
How is liquefied Class 9?
Answer: In order to liquefy a gas, the constituent particles or molecules have to be brought closer. The atmospheric gases can be liquefied either by increasing pressure or by decreasing temperature.
What is liquefaction of gas and how you can liquefy atmosphere oxygen present in air?
To liquefy a gas we need to bring the gas molecules together very close to each other. This is achieved by compressing them using high pressures. At very high pressures, the boiling point of the liquid rises. So at practically achievable temperatures, the gases can liquefy and exist as liquids.
Is it possible to liquefy atmospheric gases If yes suggest a method?
How do we liquefy the gases short answer?
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 Claude method?
A process for liquefying air on a commercial basis. Air under pressure is used as the working substance in a piston engine, where it does external work and cools adiabatically. This cool air is fed to a counter-current heat exchanger, where it reduces the temperature of the next intake of high-pressure air.
What is liquefaction of gas and how you can liquefy atmospheric oxygen present in air?
Why gases can be liquefied?
On increasing pressure the volume of the gas decreases which brings gaseous molecules together and decreases the space between them and on decreasing the temperature the kinetic energy of the molecules decreases and forces of attraction between them increases and thus, gas can be converted into liquid.
What is Linde’s method?
Linde’s process Air is liquefied by the Linde process, in which air is alternately compressed, cooled, and expanded, each expansion results in a considerable reduction in temperature. With the lower temperature the molecules move more slowly and occupy less space, so the air changes phase to become liquid.
