It means any substance that readily absorbs moisture, like from the atmosphere.
i.e wool goes by this term therefore has thermal qualities when laid as a carpet, in winter it absorbs the moist cold air leaving the atmospere in the room warmer and in summer it actually absorbs up to 30% of the humidity thus leaving it cooler.
No, but sometimes "average" means "mean" - when it doesn't mean median, geometric mean, or something else entirely.

Non-Hygroscopic
The hair of the tail of horse is hygroscopic material.
Polyol Ester is also hygroscopic
Hygroscopic substances are used to absorb humidity.
Potassium hydroxide is hygroscopic and deliquescent.
As far as I know, the PVC is not hygroscopic, it doesn't absorb the moisture. There are several types of PVC though, so there could be some hygroscopic PVC resin, but I haven't encountered it yet. Normally it is dried by hot air driers, which are not suitable for hygroscopic materials, therefore I assume PVC is not hygroscopic...
No.
Acetone is not considered hygroscopic, as it does not have a strong tendency to absorb moisture from the environment. However, it can mix readily with water, making it miscible in water.
A hygroscopic powder is a substance that has the ability to absorb moisture from the air. This property can cause the powder to clump together or become sticky. Hygroscopic powders are often used in adsorption processes to remove moisture from the environment.
Hygroscopic means that hair has a tendency to absorb and retain moisture from the surrounding environment. This property can make hair more prone to frizz in humid conditions and dryness in dry conditions.
yes.
