What phase is carbon dioxide in at 12 ATM pressure and -40C?
Both values are above Triple point at 518 kPa and −56.6 °C, so it is liquid
What happen to carbon dioxide at 10 ATM pressure as the temperature is increased from -70c-0c?
At a pressure of 10 ATM, carbon dioxide (CO2) undergoes phase changes as the temperature increases from -70°C to 0°C. Initially, at -70°C, CO2 exists as a solid (dry ice). As the temperature rises, it sublimates directly into gas without passing through a liquid phase, as the pressure is above its triple point. By 0°C, CO2 remains in the gaseous state under these elevated pressure conditions, as it does not reach the liquid phase before fully transitioning to gas.
Why is there no liquid carbon dioxide?
Liquid carbon dioxide cannot exist at pressures below 5.1 atmospheres. Below that pressure, solid carbon dioxide (dry ice) sublimates directly to a gaseous state, rather than melting to a liquid state. The average pressure at Earth sea level is 1 atmosphere, decreasing as altitude increases. So, in order to observe liquid carbon dioxide, you would have to artificially increase the pressure to over 5 times that of sea level air pressure.
What is the total pressure in ATM of 10.13 kpa nitrogen 720 mm argon 1.25 ATM of helium 780 torr oxygen and 0.92 carbon dioxide?
To find the total pressure, you need to convert all the pressures to the same unit (let's choose atmospheres). 10.13 kPa = 0.0999 ATM, 720 mm Hg = 0.947 ATM, 1.25 ATM (unchanged), 780 torr = 1.03 ATM, 0.92 ATM (unchanged) Add all these pressures together: 0.0999 + 0.947 + 1.25 + 1.03 + 0.92 = 4.247 ATM. Therefore, the total pressure is 4.247 ATM.
What phase is water in at 75 C and 9atm?
Water is in the liquid phase at 75°C and 9 atm pressure. At this temperature and pressure, water exists as a liquid due to the combination of temperature and pressure conditions present.
What phase is carbon dioxide in at 5 ATM pressure and -20?
In these conditions carbon dioxide is a gas.
What phase is carbon dioxide in a negative 60 degrees Celsius and 15 ATM pressure?
The triple point of Carbon Dioxide is 216.58 K (-56.57 °C), 518.5 kPa (5.117197 atm) so pushing the pressure higher and the temperature lower shifts it solidly into the solid phase. Another way of checking it is to note that the vapor pressure of solid Carbon Dioxide at -60 °C is 4.043 atm so increasing the pressure to 15 atm would certainly push it further into the solid phase.
Using the phase diagram for CO2, what phase is carbon dioxide in at 12 atm pressure and -40 C apex?
At 12 atm pressure and -40°C, carbon dioxide is in the solid phase according to the phase diagram. This corresponds to the region of the phase diagram where CO2 exists in the solid state at those specific pressure and temperature conditions.
Using the phase diagram for CO2 what phase is carbon dioxide in at -20C and 1 ATM pressure?
The triple point of Carbon Dioxide is 216.55 K (−56.60 °C) and 517 kPa (5.10 atm). Since that puts the pressure (1 atm) below the triple point pressure (5.1 atm) we are only concerned with the where the solid/vapor equilibrium line falls relative to the temperature. At 1 atm, the sublimation temperature of Carbon Dioxide is -78.5 °C - considerably below -20 °C so that puts the Carbon Dioxide firmly in the vapor region of the phase diagram.
What phase is carbon dioxide in at -60 degree C and 1 ATM pressure?
At -60 degrees Celsius and 1 ATM pressure, carbon dioxide would be in a solid phase. This is because the temperature is below its sublimation point, causing it to directly change from a gas to a solid without passing through the liquid phase.
What phase is carbon dioxide in at 20 degrees Celsius and 25 ATM pressure?
At 20 degrees Celsius and 25 ATM pressure, carbon dioxide would be in a supercritical state, exhibiting properties of both a gas and a liquid.
What phase is carbon dioxide in at - 20 degrees Celsius and 1 ATM pressure?
At -20 degrees Celsius and 1 ATM pressure, carbon dioxide is in the solid phase (dry ice), as it undergoes direct sublimation from a gas to a solid at temperatures below its sublimation point.
What phase is carbon dioxide in at 20C and 25 ATM pressure Using the phase diagram for CO2?
solid, I just took the text on apex
Using the phase diagram for CO2 what phase is carbon dioxide in at -60C and 15 ATM pressure?
(Explanation): If you look at the phase diagram for CO2, and you draw a lines where the temperature and pressure meet, you will see that the point will be inside the zone that is 'solid', so it is in the solid state.
What phase is carbon dioxide in at 12 ATM pressure and -40C?
Both values are above Triple point at 518 kPa and −56.6 °C, so it is liquid
What happen to carbon dioxide at 10 ATM pressure as the temperature is increased from -70c-0c?
At a pressure of 10 ATM, carbon dioxide (CO2) undergoes phase changes as the temperature increases from -70°C to 0°C. Initially, at -70°C, CO2 exists as a solid (dry ice). As the temperature rises, it sublimates directly into gas without passing through a liquid phase, as the pressure is above its triple point. By 0°C, CO2 remains in the gaseous state under these elevated pressure conditions, as it does not reach the liquid phase before fully transitioning to gas.
What happens when dry ice is warmed at 1 ATM of pressure?
When dry ice (solid carbon dioxide) is warmed at 1 ATM of pressure, it sublimes directly from a solid to a gas without going through a liquid phase. The solid dry ice turns into gaseous carbon dioxide, which expands rapidly. This process is commonly used in special effects and fog machines due to the large increase in volume.
