===Material Phases===
 
Universe Sandbox tracks three [https://en.wikipedia.org/wiki/Phase_(matter) phases] of a surface material (either water or CO<sub>2</sub>) across the surface of the object. At every [[N-Body_Simulation#Time_Step|time step]], at every point on the surface map, Universe Sandbox calculates how much of this materialwater will exist as a solid, liquid, or gas. The temperatures at which the materialwater changes between these phases (e.g., the [[Boiling Point]] or [[Freezing Point]]) depend on several properties of the object, including its [[Surface Pressure]].
 
The amount of materialwater that exists as a solid at a given point on the surface is represented by the Ice Thickness, the amount of liquid by the Water/Liquid CO<sub>2</sub>Water Depth, and the amount of gas by the Water Vapor MassPressure. LiquidWater andin the liquid or gas materialstate can also move across the surface (see below).
