1 Possible forms of nebular condensation The condensation can include two processes: gas-solid and gas-liquid-solid condensations. Because nebular condensation occurred with temperature descending slowly, the forms of solar nebular condensation is dependent on the relationship between the pressure of nebular and‘triple point’ of nebular matter. Based on vapor-condensation experiments of main silicate minerals in chondrites, Kushiro indicated that the pressure range
