The air dryer blows out moisture it has collected.
An a/c unit can also remove moisture from the air. No moisture means no condensation or frost on the wind screen. Everything is as it should be.
Moisture in the air around the glass, cup, etc.
The AC takes the moisture out of the cabin air and that helps clear the inside of the windshield from moisture faster.
Either warm the air so it can absorb more moisture, or reduce the amount of moisture in the air. No you can't. Sorry? Move its not going to happen. Come up with an invention to stop it.
A hydrometer measures moisture in the air
Air Dried Moisture
Answerevaporated water, or humidity.
The air that holds the most moisture in their air hole is warmer.
Water vapor in the air condenses when the ground cools at night. the cooler ground (often due to radiation into space when it is clear) cools the air near the ground. This cooler air cannot hold as much moisture as warm air and the moisture condenses as fog.
They come from the sunlight that's shining into the moisture-laden air in front of you. The colors are always there in the sunlight. They just have to be spread out before you can see them, and the water droplets in the air do that job.
The cold glass cools the air close to the outside of the glass and causes the moisture in the air to condense on the outside of the glass when the molecules in the air come close enough together to touch one another..
