Triple point

The triple point is the point at which a substance can exist as a solid, liquid and gas at the same time when in thermal equilibrium. In the case of water on the surface of Mars, it can only exist as either a solid or a gas, as the atmospheric pressure is too low to support liquid water. Therefore, Mars atmospheric pressure exists at pressures …
