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 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?
At first recalculate mmHg and torr to atm. Then you add them (3 values in atm.) up to get total pressure.
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.
Zinc normal phase?
Solid under standard pressure and temperature conditions (0 degree Celsius, 273 K, and 1 atm)
What is the correct pressure in kPa if the pressure is 1.54 ATM?
1.54 atm is 156kPa
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 at -60 degree C and 1 ATM pressure?
At this temperature carbon dioxide is a solid.
Using the phase diagram for CO2, what phase is carbon dioxide in at 12 atm pressure and -40 C apex?
liquid
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
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 -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 12 ATM pressure and -40C?
Both values are above Triple point at 518 kPa and −56.6 °C, so it is liquid
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.
Volume of carbon dioxide gas formed when 2.5 g calcium carbonate is dissolved in excess of hydrochloric acid at 0C and 1 ATM pressure is?
1,099 g carbon dioxide or 555.9 mL carbon dioxide gas at 1 ATM and 0 0C.
Why the dry ice cannot be melting?
Dry ice can be melted into liquid form at pressure over 5.11 times atmospheric pressure. Reference the Phase Diagram of Carbon Dioxide at http://www.science.uwaterloo.ca/~cchieh/cact/c123/phasesdgm.html (If that page is no longer available, search for the keywords "phase diagram" & "carbon dioxide") In that diagram, X is the triple-point. This is the pressure (5.11 atm) and temperature (-56.4C) at which the solid, liquid and gaseous phases for CO2 co-exist. At below that pressure (as Y with 1 atm,) CO2 changes from solid to gas as temperature increases. At above that pressure (as Z with 73 atm,) solid CO2 melts into liquid before changing to gas as temperature increases.
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?
At first recalculate mmHg and torr to atm. Then you add them (3 values in atm.) up to get total pressure.
What change in matter is caused by heat when dry ice changes into carbon dioxide?
The physical change (a phase change) is called sublimation. The liquid form of carbon dioxide exists only at higher atmospheric pressures, about 5.1+ atm.
