Answer: The water vapor content (water vapor density) in the air has a limit. Within the range of pneumatic pressure (2MPa), it can be considered that the density of water vapor in saturated air depends only on the temperature and has nothing to do with the air pressure. The higher the temperature, the greater the density of saturated water vapor. For example, at 40℃,1m³ air has the same saturated water vapor density regardless of whether its pressure is 0.1MPa or 1.0MPa.
