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 is one difference between using nuclear energy and biomass energy?
Nuclear energy does not produce carbon dioxide.
When coal burns what type of energy is it?
The chemical energy stored in the coal is converted into heat energy for space heating or to drive an engine. Coal contains carbon that mostly came from the atmosphere via the process of photosynthesis by vegetation using the Sun's energy to break down carbon dioxide in the air into carbon and oxygen. When those chemical bonds are reformed in the burning process, that solar energy is released and carbon dioxide is re-formed.
Where did the energy in wood originally come from?
The wood is made of organic carbon compounds produced when the tree grew, using carbon from the carbon dioxide CO2 in the atmosphere and energy from the Sun's light to split the carbon from the oxygen. When the wood is burnt the carbon is recombined with more oxygen from the atmosphere to produce more CO2, and the original energy which came from the Sun is then released as heat.
How do you show forces in a diagram?
You can show forces in a diagram by using force arrows
Is a motion diagram a diagram that depicts the motion of an object using images over equal time intervals?
yes

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.
How do bubbles get in to coke?
Carbon dioxide is forced into the liquid at high pressure, causing some of it to dissolve (actually, even at normal pressures some carbon dioxide will dissolve in water, but using higher pressure makes more of it dissolve).
When a lemonade bottle is opened bubbles of carbon dioxide form. Explain using Le Chatelier's Principle?
because the bubbles of carbon dioxide have a smaller density so they rise and float on top of the lemonade
What are the benefits of using carbon dioxide detectors?
Very simple: to detect carbon dioxide and to avoid accidents.
What are the disadvantages of using the new carbon dioxide dry cleaning?
The disadvantages of carbon dioxide dry cleanings are..........................................................................
What do you use carbon dioxide?
Well I use carbon dioxide in my fire extinguisher. What do you use carbon dioxide, or to put it another way? In what do you use carbon dioxide? Humans breathe out carbon dioxide... Breathing it out is not exactly using it. That would be more like making it.
Does fermentation provide energy for a cell without using carbon dioxide?
Fermentation produces alcohol and carbon dioxide. Burning the alcohol produces more carbon dioxide.
How much volume of carbon dioxide is required to be bubbled through lime water to precipitate 20 gram of calcium carbonate?
To determine the volume of carbon dioxide needed, you would need to know the stoichiometry of the reaction between carbon dioxide and calcium carbonate. In this case, since 20 grams of calcium carbonate is given, you would convert that to moles using the molar mass of calcium carbonate. Then, using the balanced equation, you can determine the mole ratio between carbon dioxide and calcium carbonate. Finally, using the molar volume of carbon dioxide gas at the given conditions (usually 22.4 L/mol at standard temperature and pressure), you can calculate the volume of carbon dioxide needed.
Using the atomic theory how the carbon dioxide in the breath that you exhale is the same as the carbon dioxide in carbonated drinks?
Yes
