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 gas in our atmosphere that causes humidity?
Water vapour. Or steam which is the gas state of water. Evaporation of water from the surfaces of rivers, lakes and mainly the oceans, an important part of the water cycle on Earth.
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.
Does water vapour have a freezing point?
Water VAPOUR literally does not have a chemical freezing point because it is in the process of evaporation which is above freezing.
What conditions in the air favor condensation of water?
saturated air and dewpoint temperature much lower than air temperature
What happened to the water vapor in the atmosphere when the early Earth cooled?
As the early Earth cooled, the water vapor in the atmosphere condensed and fell as rain, leading to the formation of the Earth's oceans. This process is known as the "primordial rainout" and it played a crucial role in shaping the planet's surface and creating the conditions for life to emerge.
Can water vapour be turned back to liquid?
Yes, in the atmosphere water vapour falls as rain.
When it reaches the atmosphere what happens to rainwater?
it becomes water vapour in the atmosphere.
Water vapour in the atmosphere is confined only to?
ionosphere
What does humidity?
Humidity is the amount of water vapour in the atmosphere
What was the compsition of early atmosphere when the Earth first formed?
Water vapour (produced rain-rivers, lakes, oceans) carbon dioxide nitrogen
What is the process by which water in plants is tranferred as water vapour to the atmosphere?
transpiration
What is the most variable in the atmosphere?
The most variable abundance in the atmosphere is Water Vapour and Ozone
What is the definition Humidity?
amount of water vapour in the atmosphere, or in a gas
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.
When does water from the lakes and oceans enter the atmosphere?
when the water turns into gas form as water vapour
What percent does water vapour of the atmosphere?
It varies. There is no single percentage value
