Why does water vapor in the air condense?
Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.
What happens to air temperature when water condenses?
The energy released when gaseous water vapor condenses to form liquid water droplets is called latent heat. Latent heat from condensation causes an increase in air temperature surrounding the water droplets. The warmer air rises, causing the water vapor to condense when it meets cooler air at a higher altitude.
Can water Vapour can exist at a temperature below?
Vapor refers to a gas phase at a temperature where the same substance can also exist in the liquid or solid state, below the critical temperature of the substance. (For example, water has a critical temperature of 374 °C (647 K), which is the highest temperature at which liquid water can exist.)
What happens when water in the air condenses?
Condensation is the process by which water vapor in the air is changed into liquid water. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized and heat is released into the atmosphere as a result.
When water is condensed its increases?
When water is condensed its volume increases. Till reaching the temperature of approximately 4 degrees Celsius, the volume of it contracts while cooling the water.
What happens at the nanoscale when water vapor condenses into liquid water?
What happens at the nanoscale when water condenses and forms a raindrop? [Water molecules in the air come together into clusters to form raindrops.] When water vapor condenses into liquid water, the behavior and arrangement of the molecules change, but all of the molecules are still there.
What happens when a substance condenses?
Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. In condensation, matter changes from a gas to a liquid. All matter is made of tiny moving particles called molecules.
What changes when a substance condenses?
During condensation, a substance is changed from the gaseous to the liquid state of matter. Vaporization, which is more often referred to as “boiling,” is the complementary process in which a chemical is converted from the liquid state of matter to a gaseous physical form.
What causes water vapour?
Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.
At what temperature does water vapour condense?
The condensation point of water is the same as the boiling point of water. This occurs at 212 degrees Fahrenheit or 100 degrees Celsius.
Where does Vapour go when it condenses?
When water vapor condenses, it is cooled down enough to turn back into a liquid and forms clouds in the air.
What happens to the motion between water molecules when liquid water transforms to a solid quizlet?
What happens to the motion between water molecules when liquid water transforms to a solid? Atoms in the liquid water move more slowly. The amount of matter stays the same as water changes state. Describe two ways that water moves through Earth’s atmosphere in the water cycle.
