The predicate object of state change is used to identify an object undergoing a change of state in an instance of event that inherently involves a change of state. (object of state change EVENT OBJECT) means that the tangible thing OBJECT undergoes some kind of intrinsic change of state (such as a change in one of its physical properties) in the event that inherently involves a change of state EVENT. OBJECT exists before EVENT, is directly involved in EVENT, and persists after EVENT (accordingly, this predicate has as Genl Preds both pre-existing actor and actor remaining afterwards). The change which OBJECT undergoes is internal or intrinsic; this predicate is not used for extrinsic changes, such as changes in location, orientation, ownership, or status. Note that if OBJECT were destroyed by EVENT and went out of existence in the course of EVENT, then the right predicate to use would be thing destroyed, rather than object of state change.
