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.
What else can I help you with?
Does vapour pressure include the partial pressure of water vapour in the atmosphere during boiling process?
The partial pressure of water (vapor) is included in the total pressure of the atmosphere (air) when boiling.
What would have more vapour pressure pure ice or sweet ice?
Both will have same vapour pressure as salt{NACL} would get trapped in ice and in solid iced state get seprated from pure ice crystals. so in case melting of ice in soln state pure water will have more vapour pressure but in solid state both will have same vapour pressure.
What is the unit of true vapour pressure?
The unit of true vapour pressure is typically expressed in millimeters of mercury (mmHg) or kilopascals (kPa).
What is the vapour pressure of liquids?
Vapour pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. It is a measure of a liquid's tendency to evaporate. The higher the vapor pressure, the more volatile a liquid is.
What is the effect of the temperature on the vapour pressure?
When temperature is increased the amount of molecules evaporated is increasef and as a consequence condensation is also increased so vapour pressure increases.
Do people only exhale CO2 and water vapour?
no
Does the evaporation in the evaporation column influence the total pressure?
evaporation as such influence on the total pressure. evaporation occurs when the total pressure is greater than the surface molecules vapour pressure. as the rate of evaporation increases , more vapour will be there at the top, and then the new total pressure will become the sum of the earlier total pressure and vapour pressure of the vapour evaporated. hence total pressure increases.............
Does vapour pressure include the partial pressure of water vapour in the atmosphere during boiling process?
The partial pressure of water (vapor) is included in the total pressure of the atmosphere (air) when boiling.
What is the condition which occurs when the atmospheric pressure is equal to the vapour pressure?
boiling
What would have more vapour pressure pure ice or sweet ice?
Both will have same vapour pressure as salt{NACL} would get trapped in ice and in solid iced state get seprated from pure ice crystals. so in case melting of ice in soln state pure water will have more vapour pressure but in solid state both will have same vapour pressure.
What is the unit of true vapour pressure?
The unit of true vapour pressure is typically expressed in millimeters of mercury (mmHg) or kilopascals (kPa).
What is in the troposphere?
Contains normal air composed of N2, O2, water vapour, CO2, etc.
Absolute vapour pressure?
Sir yes sir!
What is the diesel reid vapour pressure?

When smelling a liquid?
When this liquid has a great vapour pressure.
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
