Aprocess stream of pure methanol liquid enters a heat exchanger at 25°c and leaves as a vapor at 100°c. if methanol gas at 25°c were used instead at the same mass flow rate, the amount of heat required to reach 100°c would be

Silica, sio2, is formed on silicon as an electrically insulating layer for microelectronic devices. silica is formed when silicon is exposed to o2 gas at an elevated temperature. at 900˚c, it takes 90 minutes for the oxygen to diffuse from the surface to form a 0.06 micron (0.06 x 10-6 m) thick layer of sio2 on
