do you have homeschool that your asking this because i do and im looking for the same answer
A substance that is in the gas phase at a temperature at which it would normally be a solid or liquid
Yes. The phase of matter which is exposed to normal atmospheric pressure solely dependent upon temperature.
Phase diagram?
The phase of a substance is dependent on several things. Most basically, the composition of the substance itself and the strength of the atomic interactions within the substance determine how the other factors will effect it. For example, these interactions determine that water is liquid and steel is solid at room temperature. Substances changing phase depends on the temperature and the pressure exerted on them. The higher the temperature, the closer a substance gets to a gaseous phase. The lower the pressure, the same. This is the reason why water boils at a lower temperature if you are at a significantly higher elevation: there is less pressure. An interesting concept which has cool applications is that of a "triple point." Use Google to find a graphic image, so you can more easily figure out what I am saying. The triple point is the place at which the three phases meet, and each substance has its own triple point at a unique temperature and pressure. Below this point in temperature, pressure, or both, a substance will skip the liquid phase entirely and go directly from a solid to a gas, as in the case of "dry ice."

"A phase diagram is a graph of pressure versus temperature that shows in which phase a substance exists under different condition of temperature and pressure" -Glencoe Chemistry Book

Yes. The phase of matter which is exposed to normal atmospheric pressure solely dependent upon temperature.
A phase diagram shows if a substance is going to be a solid gas, or liquid at a combination of pressure and temperature. It states what phase of matter a substance is at a specific temperature.

This depends on the temperature.
