What does water condenses into?
Water evaporates into water vapour, and water vapour condenses into water.
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.
Why anhydrous copper II chloride is used to test for the presence of water?
Anhydrous copper II chloride is used to test for the presence of water because it readily absorbs moisture. When anhydrous copper II chloride reacts with water, it forms a blue-green hydrated copper II chloride compound, helping to detect the presence of water by a visible color change.
Cobalt chloride paper test?
The cobalt chloride paper test is a simple test used to detect the presence of moisture in a given sample. When it comes into contact with water, cobalt chloride changes color from blue to pink. This paper test is commonly used in science experiments and as a qualitative indicator for water in various substances.
How do you prove the presence of water vapour In air?
take a very cold beverage out of the fridge and let it sit on the counter for a minute or two, if you are not in an air conditioned building there should be condensation on the surface of the can, proving that water vapor is in the air.
How can you detect presence of water vapour?
By using cobalt chloride paper. The acidity of the water would change the color of the paper due to the Ph balance.
How do sharks detect the presence of food?
When they can smell blood in the water.
What does emulsion test detect?
The emulsion test is used to detect the presence of lipids (fats) in a substance. It involves mixing the test substance with ethanol and water to form an emulsion. The presence of a white emulsion indicates the presence of lipids.
How do you prove that water vapour is present in the air by using only a beaker and several ice cubes?
Place the ice cubes in the beaker and wait for a few minutes. If water droplets form on the outside of the beaker, it indicates that water vapor in the air has condensed on the cold surface of the beaker. This condensation process proves the presence of water vapor in the air.
What test can be used to detect substance of emulsion?
A drop test can be used to detect the presence of an emulsion. Add a drop of the emulsion to water. If it disperses or forms a milky appearance, it indicates the presence of an emulsion.
How do you detect water vapour in the air?

Why is it necessary to make periodic chemical and bacteriological analysis of water used for drinking?
To detect the presence of poisionous elements such as lead and to detect if there is contamination of the water source of harmful bacteria such as E Coli
Can water vapor rust iron?
Rusting will only occur in the presence of both water and oxygen. In the presence of oxygen, water vapour in the air will cause rusting to occur. So unless you are talking about the iron coming into contact with water vapour but when there is no oxygen, the answer is yes.
How do you watch weather from space?
There are weather sattellites that orbit the Earth that can detect reflected radiation, emitted radiation, or radiation reflected only by water vapour as well as satellites that emit microwave radiation to detect the clouds or precipitation.
What is water turned into gas called?
It is called water vapour or simply vapour.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
What does water vapour do?
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.
