Hygroscopic Definition and Examples

The definition of hygroscopic is having the property of absorbing or adsorbing water from the environment. Hygroscopic means capable of attracting and holding water from environment, either through absorption or adsorption. Typically, this process occurs near ambient or room temperature. Hygroscopy is the ability to attract and hold water. Both terms originate …
