Differential scanning calorimetry was used to analyze the effects of confinement on the glass transition of temperature, T{sub g}, of several molecular liquids in porous silica glasses. For all the liquids, confinement lowers the observed T{sub g}. A linear relationship between the inverse of the silica glass pore radius and T{sub g} was also observed. The relative temperature depression due to confinement was less than the freezing point depression. 40 refs., 1 fig., 1 tab.
