Solid [[carbon dioxide]] ([[dry ice]]) sublimes rapidly along the solid-gas boundary (sublimation point) below the triple point (e.g., at the temperature of −78.5&nbsp;°C, at [[atmospheric pressure]]), whereas its melting into liquid CO<sub>2</sub> can occur along the solid-liquid boundary ([[melting point]]) at pressures and temperatures above the triple point (i.e., 5.1 atm, −56.6&nbsp;°C).
