As you can see below, I'd like to know why the saturation is decreasing with the temperature while the absolute amount of water remains constantly. The image is taken from a description of a transformer where the relative humidity in oil is decreasing with the temperature, so I'd be happy if an explanation could fit to the image.
I asked a similar Why has warm air a higher water saturation than cold air? but meanwile I think it doesn't really explain the reason. But maybe I miss the forest for the trees.
However: Why is the relative humidity decreasing with the (oil) temperature?
