How does gravity affect condensation?
Well, if you increase the pressure of the atmosphere, isothermally, around water high enough, then you will overcome the 'vapour pressure' of the water, or the pressure of the water's surface back on the atmosphere to put is very, very simply. SOOOO, if you increase gravity, then you increase atmospheric pressure, which will condense any water vapour in the air. You can decrease gravity to see that the vapour pressure of the newly condensed liquid water will overcome the atmospheric pressure and vaporize. Keep in mind this works in standard conditions, not at extreme temperatures and pressures.
What conditions in the air favor condensation of water?
saturated air and dewpoint temperature much lower than air temperature
What is water vapor in the air?
Water vapor in the air is water in the form of a gas.
Why does dew appear in early morning and not at noon?
the air capacity for holding water depends on temp'. the warmer it is the more water vapour it can hold. during the night air temp' drops to its lowest near dawn at which point the amout of water vapour in the air may exceed its reduced capacity (this point is called the dew point) and water vapour condences and forms dew.
What does changing the air pressure have a greater affect on the balloons volume rather than the air pressure?
The logic of the question appears contestable - can we try again.
What is relative humidity a ratio of?
Relative humidity is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure. Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.
What is the ratio of RH?
Relative humidity (RH) is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure. Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.
What is the water vapour pressure of expired air?
47mmHg @ 37oC
Does vapour pressure include the partial pressure of water vapour in the atmosphere during boiling process?
The partial pressure of water (vapor) is included in the total pressure of the atmosphere (air) when boiling.
What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
How is relative humidity affect by air temperature?
Warmer air is able to hold more water vapour than cooler air. As warm humid air cools, the water vapour condenses out as water droplets.
What refers to the amount of water vapour in the air?
Relative Humidity is the measure of water vapour in air. It is the ratio of the actual water vapour in air divided by the maximum amount the water the air can hold at the existing temperature and pressure. It tells how fast or slow the water on the body or in clothes will evaporate or in otherwords is the air dry or humid. Absolute measure of water vapour in air is called specific humidity. It can be measured as ratio of mass of water and mass of dry air.

What is 10 percent humidity?
At any given pressure and temperatire, a volume of air can hold a certain amout of water vapour before is begins to condense out (into water droplets). 10% humidity means that the amount of water vapour in the air is 10% of what the air could hold at that pressure and temperature.
How do you get dew point?
Cool air at a constant pressure until it is saturated with water vapour
Relative humdity is a ratio of what?
The mass of water vapour in a given quantity of air to the maximum mass of water vapour that it could hold - at the specific temperature and pressure.
What are the factors affect air pressure?
Three factors that affect air pressure are temperature, altitude, and water vapor.
