The moisture equilibrium chart can be used to determine the __________.

Correct Answer: Option D — Dew point temperature that the air surrounding a hygroscopic commodity will have when in moisture equilibrium with that commodity

Hygroscopic cargo gives off or absorbs moisture until it reaches equilibrium with surrounding air. The moisture equilibrium chart directly relates cargo moisture content to the resulting dew point of the interstitial or hold air, preventing cargo damage during transport per standard marine cargo operations.
