When water heats up, it rises as vapor and as temperature drops at high altitudes, the vapor condenses and becomes clouds. With time, the condensed water soon liquidifies and becomes rain.
Water vapour in the air - condenses onto surrounding surfaces when the temperature drops.
If it happens in a cloud, the drops combine until too heavy, and it rains.
Because that's where the exhaust temperature drops so how that that the water vapour in the exhaust can condense into rust-promoting water.
As soon as the temperature drops below the dew point, water will condense from water vapor.
This could be interpretted several ways. The atmosphere is not uniform, there are areas of high and low pressure, humidity and temperature. So for hot places water vapour rises into the atmosphere, wind travels down a pressure gradient and the temperature drops causing the water vapour to condense until it is too heavy and falls down as precipitation.
Dew is Condensed Water Vapour so LIQUID
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
No, dew is liquid water and it forms when the air temperature drops sufficiently that the air can no longer hold all its water vapour. This must be above freezing point. Of course the same argument applies when the temperature does drop below zero, but then we get ice crystals instead of water drops, and we call it frost.
supersaturation of water vapour leads to the formation of ice crystal
Droplets of water will condense on a surface when the surface drops below the Dew Point temperature at that relative humidity.That is, the vapour condenses into a liquid phase. The droplet shape is caused by surface tension of the liquid.
It drops during hibernation
When the temperature drops the less water vapor in the air
