The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the carbon dioxide boiling point with changes in pressure.

Carbon dioxide is a chemical compound with the chemical formula CO 2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature and at normally-encountered concentrations it is …

In addition, carbon dioxide reacts with water in the body to form carbonic acid, which dissociates to hydrogen ion and bicarbonate. An increase in carbon dioxide in the body increases acidity, and then the kidneys act to restore normal acidity.

The boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure. The boiling point at atmospheric pressure (14.7 psia, 1 bar absolute) for some common fluids and gases can be found from the table below:

‡Second column of table indicates solubility at each given temperature in volume of CO2 as it would be measured at 101.3 kPa and 0 °C per volume of water. The solubility is given for "pure water", i.e., water which contain only CO 2. This water is going to be acidic. For example, at 25 °C the pH of 3.9 is expected (see carbonic acid).

Carbon dioxide has no liquid state at pressures below 5.1 atm. At 1 atm it is a solid at temperatures below −78 °C. In its solid state, carbon dioxide is commonly called dry ice. CO 2 is an acidic oxide: an aqueous solution turns litmus from blue to pink.

Feb 2, 2011 · Carbon Dioxide (CO 2) is a colorless, odorless and nonflammable gas heavier than air. It is classified as one of the major air pollutants when it exceeds its naturally-occurring concentration. There are a number of processes for its production including combustion, fermentation and heating of organic matter.

Feb 3, 2025 · Carbon dioxide, a colorless and odorless gas, exhibits distinct physical properties in terms of melting and boiling points. At a temperature of -78.5 degrees Celsius or 194.6 degrees Fahrenheit, carbon dioxide solidifies into a solid state.
