What does water vapour mean?
water vapor. Water in its gaseous state, especially in the atmosphere and at a temperature below the boiling point. Water vapor in the atmosphere serves as the raw material for cloud and rain formation.

What process is water vapor?
Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
What is water vapour short answer 6?
Water vapour comes into the air from the evaporation of water present on the earth (in ponds, lakes, rivers and oceans, etc.) and from transpiration. It is water vapour present in air which rises high in the sky along with hot air, gets cooled, condenses to form clouds and then brings rain on the earth.
Are clouds water vapor?
While it’s true that clouds contain water, they actually aren’t made of water vapor. … The air around us is partially made up of invisible water vapor. It’s only when that water vapor cools and condenses into liquid water droplets or solid ice crystals that visible clouds form.
What is water vapor and why is it important?
Water vapor is also the Earth’s most important greenhouse gas, accounting for about 90% of the Earth’s natural greenhouse effect, which helps keep the Earth warm enough to support life. When liquid water is evaporated to form water vapor, heat is absorbed. This helps to cool the surface of the Earth.

What is the opposite of vapor?
Opposite of matter in a state intermediate between liquid and plasma. liquid. solid.
Where does condensation occur?
The Condensation Process Condensation occurs when warmer moist air comes in contact with cold surfaces such as framing members, windows and other accessories, or the colder region within the insulation envelope (if moisture has penetrated the vapor retarder).
What causes condensation of water vapor?
What causes condensation? … For condensation to form, water vapor is either cooled to its dew point – which is the temperature at which water in the air condenses to create water droplets. Or, the air becomes so saturated with water vapor that it can’t hold any more water.
Where does water vapor in the air come from?
Under normal circumstances, water vapor enters the atmosphere through evaporation and leaves by condensation (rain, snow, etc.). Water vapor also enters the atmosphere by a process called sublimation. That occurs when water vapor moves into the air directly from ice without first becoming water.
What is water vapour short answer 7?
– Water vapor is water in its gaseous state-instead of liquid or solid.It is totally invisible. – When the air gets saturated with the water vapour, at a specific temperature it will form frost as it starts to condense.
What is dust 6th?
Dust is the small particles suspended freely in the air. Smoke is made up of water vapour and gases which pollute the air.
What is condensation class 6th?
Condensation is a process of changing of a substance from vapour to liquid on cooling. … So liquid form of water is changing into vapour form.
Is water vapor a gas?
Water existing as a gas is called water vapor. When referring to the amount of moisture in the air, we are actually referring to the amount of water vapor. If the air is described as “moist”, that means the air contains large amounts of water vapor.
Is water vapor visible or invisible?
Water vapor is the gas state of H2O and is invisible. The air around you on a humid summer day is chock full of water vapor, but you don’t see any of it. On the other hand, there is very little water vapor in the air during the cold of winter, yet you can easily make clouds with your breath.
Is steam water vapor?
Steam is an invisible gas, unlike water vapor, which appears as a mist or fog.
What is the difference between water vapor and water?
Water vapor just means the gas form of water. Water is a molecule, not specifically a liquid.
What is difference between steam and water Vapour?
Water vapor is little water droplets that exist in the air, while steam is water heated to the point that it turns into gas. In simplified science, both are referred to as the gaseous state of water. However, the main difference between them lies in temperature.
What is called humidity?
The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.

What is the difference between dew and frost?
Dew is liquid moisture on the ground that is seen in the morning. … Frost forms is the same way as dew except it occurs when the dewpoint is below freezing. True frost forms when the temperature is below freezing. The moisture goes straight from a gas to a solid.
What causes dew at night?
Dew forms as temperatures drop and objects cool down. If the object becomes cool enough, the air around the object will also cool. Colder air is less able to hold water vapor than warm air. … Warm, humid air is full of moisture that can condense during calm, cool nights.
How do clouds form?
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.
What is it called when water vapor up in the sky becomes liquid water?
Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.
What are clouds made of?
A cloud is made of water drops or ice crystals floating in the sky. There are many kinds of clouds. Clouds are an important part of Earth’s weather.
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.
What happens water vapor?
When water vapor in the atmosphere loses heat and cools down, condensation happens. As the water vapor cools down and condenses, it attaches to small particles of dust floating in the atmosphere, forming tiny liquid water droplets. … When condensation occurs on the ground, it forms dew.
Is water vapor still H2O?
Water vapor still has the same chemical formula as typical water – H2O – but the water molecules in vapor interact less with one another and are not as structured as they are in water and ice. Whether or not water will be in liquid or gas form is dependent on pressure, temperature, and relative humidity.
