How is liquid CO2 made and what is the process involved in its production?
Liquid CO2 is made through a process called carbon capture and storage (CCS). This involves capturing carbon dioxide gas from industrial processes or power plants, compressing it to a high pressure, and then cooling it to a low temperature to turn it into a liquid state. The liquid CO2 can then be stored or transported for various industrial uses.
What does one liter of liquid CO2 weigh in pounds?
Is that a trick question? CO2 does not have liquid phase as it goes from solid to gas
Is H2O warm water and CO2 cold water?
H2O is the chemical formula for water, whether it is warm or cold. CO2 is the chemical formula for carbon dioxide, which is a gas and not water. Temperature affects the state of water (solid, liquid, or gas) but not its chemical composition.
Why CO2 it is in gas status?
Carbon dioxide (CO2) is in a gas state at room temperature and pressure because its molecules are not compact enough to form a liquid or solid. The weak intermolecular forces between CO2 molecules allow them to move freely and remain in the gaseous state.
Why carbon dioxide is liquefied to give liquid carbon dioxide is physical change?
Changes of state, such as solid to liquid, or liquid to gas, are physical changes because no chemical reaction occurs. CO2 as a solid, a liquid, or a gas is still CO2. Generally, physical changes are easily reversed, so that if carbon dioxide is condensed from a gas to a liquid, it is easy to evaporate it back into a gas.

Why liquid CO2 vaporise and convert in to dry ice?
Liquid CO2 vaporizes and converts into solid dry ice because of the decrease in temperature to below -78.5°C and the increase in pressure above 5.1 atm. These conditions cause the CO2 molecules to rearrange into a solid state without passing through a liquid state, a process known as deposition.
How do phase diagrams for water and carbon dioxide differ?
both have a solid, liquid, and gas phase. it's just that to get CO2 in the liquid phase takes a lot of effort and is highly reactive in terms of it quickly evaporates to the preferred state of gaseous CO2.
What happens when liquid co2 is exposed to air?
When liquid CO2 is exposed to air, it quickly evaporates and turns into gaseous CO2. This process is known as sublimation. The gaseous CO2 will mix with the air in its surroundings.
If you cool carbon dioxide below -78.5 C in what state will it be?
If u cool CO2 b low -78.5 C it will melt in2 a liquid. ( at -78.5 C CO2 sublimates )
To covert in to vapor means?
To convert into vapor means to cause a substance to change from a solid or liquid state into a gaseous state. For example, boiling water vaporizes into steam......dry ice (solid CO2) vaporizes directly into CO2 gas
What does one liter of liquid CO2 weigh in pounds?

What is the expansion ratio of CO2 from liquid to gas at the same temperature and pressure?
The expansion ratio of carbon dioxide (CO2) from liquid to gas at the same temperature and pressure is approximately 1:800. This means that one volume of liquid CO2 will expand to about 800 volumes of gaseous CO2 when it vaporizes. This significant expansion highlights the dramatic change in density between the liquid and gaseous states of CO2.
From what state does sublimation change to?
Sublimation causes a change from solid straight to liquid or vica-verca, skipping the liquid phase altogether. Examples are mothballs and dry ice (frozen CO2).
What happens when dry ice is warmed at 1atm of pressure?
When dry ice is warmed at 1 atm of pressure, it sublimes directly from a solid to a gas without passing through the liquid state. This means it goes from a solid CO2 to gaseous CO2 without melting into liquid CO2 first.
What is the symbol state of CO2?
The symbol state of carbon dioxide (CO2) is typically represented as a gas (g) at room temperature and pressure. In chemical equations, it is often written as CO2(g) to indicate its gaseous form. However, under high pressure or low temperatures, CO2 can exist as a solid (dry ice) or liquid, but in standard conditions, it is most commonly encountered as a gas.
Which substance will sublime at 298K?
Iodine sublimes at 298K. Sublimation is the process in which a substance transitions directly from a solid to a gas without passing through the liquid state.
