When water vapour cools sufficiently, it can form liquid water. This is called condensation. If it is cooled below zero degrees Celsius it can form ice. This is also condensation. An example of the first one is droplets of water forming on a cold window, and an example of the second is frost.
What else can I help you with?
Is water vapor condensing on a cold window a physical or chemical change?
Water vapor condensing on a cold window is a physical change. It is simply a change in state from a gas (water vapor) to a liquid (water) due to the temperature difference. No new substances are formed during this process.
How does vapor pressure of water at 50 oC compare with its vapor pressure at 50 oC?
The saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
At what temperature does water vapor condense?
Water vapor condenses into liquid water at its dew point temperature.
At what temperature does water vapor in air condense?
Water vapor in air condenses into liquid water at the dew point temperature.
WHAT DO YOU CALL THE CHANGE FROM STEAM OR WATER VAPOR BACK TO LIQUID?
The change from steam or water vapor back to liquid is called condensation. This process occurs when the vapor cools down and turns into liquid droplets due to a decrease in temperature.
Is water vapor condensing on a cold window a physical or chemical change?
Water vapor condensing on a cold window is a physical change. It is simply a change in state from a gas (water vapor) to a liquid (water) due to the temperature difference. No new substances are formed during this process.
What are the four variables that can change the air?
temperature,volume,height and, water vapor
If you have measured the temperature of the air and have found it to be 75o F with 80 percent relative humidity If the amount of water vapor that was contained in the air at that time does not change?
If the amount of water vapor in the air does not change, the relative humidity will remain at 80% as long as the temperature remains constant at 75°F. If the temperature changes, the relative humidity will change, as it is dependent on both temperature and the amount of water vapor in the air.
How does vapor pressure of water at 50 oC compare with its vapor pressure at 50 oC?
The saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
What is a frozen water vapor that falls to earth as flakes called?
Frozen water vapor that falls to earth as flakes is called snow.
Which process changes liquid water into water vapor?
boiling will change all water being boiled fairly quickly into water vapor. Exposed water of any temperature will slowly become water vapor by way of evaporation.
when water vapor is change into water droplets in the air are formed?
water vapor change into water droplets when are at a low temperature. when the water vapors are at a low tempertaure, the particles of water come closer to each other and they form droplets of water.
Why does temperature of water does not change when it boils?
because all the energy supplied goes out with the vapor !
At what temperature does water vapor condense?
Water vapor condenses into liquid water at its dew point temperature.
How and why is clouds forming in the sky a physical change?
because condensation is simply just a change of the water temperature in the air. a temperature change is a physical change. clouds form when the water vapor condenses, so therefore, cloud formation is a physical change.
How does temperature affect amount of vapor in the air?
The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.
Does water vapor change to liquid water?
when water vapor turns to liquid water, it needs to condensate, when its temperature goes below 100 degrees, which is water's boiling point, for it to turn into liquid.
