Witryna2 gru 2024 · When energy is lost from a substance, the temperature drops, causing it to change from liquid to solid (freezing), gas to solid (deposition), or gas to liquid (condensation). When the pressure applied to a substance increases, the substance can condense. It can vaporize if the pressure is reduced. Witryna25 paź 2013 · In severe operating conditions (high gas pressure/high temperature), the chemical activity towards potentially reactive atmospheres (water, CO 2, etc .) is enhanced. This can lead to mechanical, chemical, and structural instability of the membranes and premature efficiency loss.
