What method is used to separate noble gases and air?
Fractional distillation is used to separate noble gases and air, by first liquifying the air and allowing the individual gasses to evaporate out at their respective boiling temperatures.
How do we remove co2 from a mixture of gases?
Carbon dioxide can be removed from a mixture of gases through various methods such as absorption, adsorption, membrane separation, or cryogenic distillation. These processes selectively capture CO2 molecules from the gas mixture, allowing for separation and removal.
Why is air a simple substance?
Air is considered a simple substance because it is a homogeneous mixture of gases, primarily nitrogen, oxygen, and trace amounts of other gases. It does not have a fixed chemical composition and can be easily separated into its individual components through methods such as distillation or fractional crystallization.
Where does gases have cooled?
Gases cool down when their temperature decreases, causing their particles to slow down and lose energy. This cooling process can occur naturally in the atmosphere, as in the case of air cooling at higher altitudes, or artificially through methods like refrigeration or expansion cooling.
Can gasses be contained?
Yes, gases can be contained using various methods such as pressurized containers, sealed vessels, or inert atmospheres. When properly contained, gases can be stored, transported, and used safely in various industrial, scientific, and everyday applications.
What method is used to separate noble gases and air?
Fractional distillation is used to separate noble gases and air, by first liquifying the air and allowing the individual gasses to evaporate out at their respective boiling temperatures.
What is a scientific word for melt?
the scientific word for melting is liquifying. the scientific word for melting is liquifying.
How do you seaperate gases?
Based on their volatility,temperature,pressure gases can by separated by different methods Eg: chromatography vaporisation crystallization etc..........
How can you observe gasses without seeing them?
You can observe gases through indirect methods such as detecting their odor, measuring changes in temperature, or using chemical indicators that react in the presence of specific gases. These methods can help in identifying the presence and characteristics of gases without seeing them directly.
Is liquifying nitrogen a chemical change?
It is a chemical change because it can change back if you refreeze the nitrogen and it changed the chemical.
Does cooking reduce or add greenhouse gases?
Cooking technically adds greenhouse gases. The vapors and gases produced through the cooking process do add to greenhouse gases, but certain methods of cooking are worse than others.
How is the measurement of greenhouse gases conducted?
The measurement of greenhouse gases is conducted using various methods, including ground-based monitoring stations, satellite observations, and air sampling. These methods help scientists track the levels of greenhouse gases in the atmosphere over time and understand their impact on the Earth's climate.
How are gases measured and what methods are used to determine their quantity?
Gases are measured using instruments like gas analyzers, gas detectors, and gas meters. These devices can determine the quantity of gases by measuring factors such as pressure, volume, temperature, and concentration. Common methods include gas chromatography, mass spectrometry, and infrared spectroscopy.
Can this method be used for gases?
It depends on the specific method you are referring to. Some methods can be used for gases, while others are designed for liquids or solids. It's important to check the applicability of the method to gases before use.
What is the scientific of saying melting?
The transformation from a solid to a liquid.
What has the author H W Melville written?
H. W. Melville has written: 'Experimental methods in gas reactions' -- subject(s): Chemical reactions, Gases, Kinetic theory of gases
Where are ions and free particles formed?
Ions can be formed in solutions by dissociation, in gases by different methods of ionization, etc.
