Glucose dissolves in water but doesn’t produce ions during dissolution process. Two (positive and negative) electrodes that were hooked up to a light bulb and external source of power were placed in an aqueous solution of glucose. What was observed during experiment?

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.

You know how the first one if filled up like the objects do the same but with the other categories

Yes it would be a physical change.
