What is the concentration of carbon dioxide when monomer burns?

It depends on what fire is put out. Generally, at room temperature and 30% ~ 60% pressure, carbon dioxide (CO2) exists in gaseous form, with a molecular weight of 48 and a unit volume weight of about 1.5 times that of air. Colorless (a large amount of carbon dioxide gas is milky white or smoky gray when gathered together), odorless, and does not react with metals and combustible substances. A certain amount of carbon dioxide in the air will produce a greenhouse effect to a certain extent.

The critical temperature of carbon dioxide is 3 1.4℃, the critical pressure is 7.4MPa (absolute pressure), the storage point temperature of solid, liquid and gas is -56.6℃, the pressure is 0.52 MPa (absolute pressure), and the carbon dioxide between the critical point and the triple point is gas.
