When is carbon dioxide a liquid?

Answer 1

Carbon Dioxide does not turn into a liquid. It changes state from a gas to a solid or solid to a gas. This is called sublimation. It does not enter the state or liquid which is unusual. This applies when the carbon dioxide is subjected to standard pressure. However, there is a way of manipulating the pressure on the carbon dioxide to give it a liquid state of matter.

The critical temperature for carbon dioxide is 88 degrees Fahrenheit. This is the maximum temperature at which carbon dioxide can be a liquid. Therefore, the temperature must be below 88 degrees Fahrenheit to keep it at a liquid state. The carbon dioxide must be pressurized to at least 5.1 ATM to remain a liquid no matter how cold.

Answer 2

If it is a gas then it is neither a liquid nor a solid! C02 is rarely a liquid (you need special high pressure and appropriate temperatures to get the liquid phase) See: http://en.wikipedia.org/wiki/File:Carbon_dioxide_pressure-temperature_phase_diagram.svg.

At -78°C the gas deposits directly into the solid phase (and at that temperature it sublimes from solid to gas).

Answer 3

No,it is a gas but under pressure it solidifies

Additional answer

It also solidifies if you cool it to 78.50C without pressure. It's used like this as 'dry ice' in some refrigerators.

Answer 4

Yes it can.

If you compress and cool CO2 and store it in a tank, it will be in liquid form. As far as transitioning from solid to liquid to gas, no. CO2 skips the liquid state and transitions directly from the solid state to gas in a process that is known as sublimation.

Answer 5

The critical temperature for carbon dioxide is 88 degrees Fahrenheit. This is the maximum temperature at which carbon dioxide can be a liquid. Therefore, the temperature must be below 88 degrees Fahrenheit to keep it at a liquid state. The carbon dioxide must be pressurized to at least 5.1 ATM to remain a liquid no matter how cold.

Answer 6

• Carbon dioxide gas deposits directly to a solid at temperatures below −78.5 °C and the solid sublimes directly to a gas above −78.5 °C.
• In its solid state, carbon dioxide is commonly called dry ice.
• Carbon dioxide has no liquid state at pressures below 5.1 standard atmospheres (520 kPa).

Answer 7

Carbon dioxide is a liquid under high pressure and low temperature conditions. This occurs when the pressure is above 5.1 atm and the temperature is below -56.6 degrees Celsius.

Answer 8

Elemental Carbon is a solid. It can form Carbon Dioxide which is either a solid or a gas. It can form Alcohol which is a liquid

Answer 9

At -56.6 degrees Celsius, you need 5.1 atmospheres. Colder than -56.6 degrees Celsius, the liquid carbon dioxide will freeze solid.

Answer 10

-78.5 degrees Celsius

Its known commonly as Dry Ice
