Final answer:
No, liquid water would typically not be visible in a membrane-type humidifier chamber as it converts water into vapor through a semi-permeable membrane without allowing liquid water to enter the air.
Step-by-step explanation:
If we consider a membrane-type humidifier, the design is such that liquid water is typically not visible within the humidifier chamber. These types of humidifiers work by allowing water vapor to diffuse through a semi-permeable membrane. Due to this process, liquid water is generally not present within the chamber because it is converted into water vapor before reaching the air. The purpose of this design is to increase the humidity of the surrounding air without producing liquid droplets that can carry minerals or bacteria.
