What is the density of CO2 at 400 deg C?
The density of carbon dioxide at 400°C will depend on the pressure it is under. At standard atmospheric pressure (1 atm), the density of CO2 at 400°C is approximately 10.26 kg/m^3.
Why solid co2 is stored under high pressure?
Solid CO2, also known as dry ice, is stored under high pressure to contain its sublimation process. Dry ice turns directly from a solid to a gas at normal atmospheric pressure. Storing it under high pressure helps to maintain its solid form for longer periods.
What is the vapour pressure of CO2?
The vapor pressure of carbon dioxide (CO2) at 25°C (77°F) is approximately 5.2 atmospheres (atm). This pressure can vary with temperature; for example, at higher temperatures, the vapor pressure increases. CO2 sublimates at temperatures below its triple point, which is around -56.6°C (-69.9°F) at 5.2 atm, meaning it transitions directly from solid to gas without becoming liquid under standard atmospheric conditions.
Is photosynthesis responsible for atmospheric CO2?
Photosynthesis is responsible for lowering the levels of atmospheric CO2 since it is a requirement to make glucose. Cellular respiration produces CO2 as a by-product, so it is responsible for some atmospheric CO2.
Is a carbonated drink a mixture of two immiscible liquids?
No. It is a supersaturated solution of carbon dioxide in whatever it is you're drinking. The CO2 stays in solution because at the top of the container, there is CO2 at high pressure. When you open the container, the pressure in it drops to atmospheric pressure and the dissolved CO2 bubbles its way out of solution...which is what you want it to do.
How do you convert 1 ton of CO2 to cubic feet?
To convert 1 ton of CO2 to cubic feet, you would need to know the density of CO2 at the given temperature and pressure. Typically, at room temperature and atmospheric pressure, 1 ton of CO2 is approximately equivalent to 515 cubic feet.
What is the density of CO2 at 400 deg C?
The density of carbon dioxide at 400°C will depend on the pressure it is under. At standard atmospheric pressure (1 atm), the density of CO2 at 400°C is approximately 10.26 kg/m^3.
Why CO2 gas comes out in force when bottles of soda is opened?
The cause is the pressure difference between the gas pressure in the bottle and the atmospheric pressure.
The vapor pressure of CO2 is lower than the vapor pressure of water?
No, the vapor pressure of CO2 would be higher. Think of it like this, if you compress the molecules in gas enough, they will be close enough together to form a liquid. Both CO2 and water can exist as liquids and gas. At atmospheric pressure (14.7psi) or normal everyday pressure, water is a liquid and CO2 is a gas. This means that 14.7psi is not enough pressure to compress CO2 into the liquid state. Therefore, CO2 has a higher vapor pressure because it requires more pressure to become a liquid. Looking at it from the other side, if you had extremely high pressure where CO2 and water were both liquids and you started lowering the pressure, CO2 would become a vapor first once you went below a certain high pressure, and water wouldn't become a gas until you went well below atmospheric pressure.
What type of reaction is hydrogen and nitrogen gases react to make ammonia used in fertilizer?
Natural gas plus steam plus atmospheric air under pressure=> NH3 + CO2
How is carbonic acid formed?
Carbonic acid (H2CO3) is formed when carbon dioxide is dissolved in water under pressure. But carbonic acid is unstable, and under atmospheric pressure, decomposes to water and carbon dioxide. H2O + CO2 ---> H2CO3

Does a partial rebreather mask breath in CO2?
yes but only the ambient CO2 it is a NITROX mask for elevated O2 between 40 and 60 % the rest is AIR which contains Co2 at atmospheric pressure.. 1 BARAdditionAssuming you are talking about some kind of full face diving mask with a regulator attached, you will be rebreathing some gas you have exhaled. So yes, you will be rebreathing CO2 - which will be at a greater concentration as well as a greater partial pressure than the CO2 at atmospheric pressure. But it will be minor amounts. However if you are talking about a hospital type of application then it is a different answer.
Which gas can be liquefied under pressure at ordinary temperature?
Carbon dioxide (CO2) can be liquefied under pressure at ordinary temperature.
Under which conditions is more CO2 dissolved in a carbonated beverage?
More CO2 is dissolved in a carbonated beverage when the beverage is under high pressure and low temperature.
How does soda fizz?
The carbon dioxide (CO2) in carbonated beverages is dissolved in the water under pressure and result in a bubbly fizz which is the CO2 being released as the pressure is reduced.
