What is the element presence of water?
water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states.
Where does condensation take place?
Condensation is the change of water from its gaseous form (water vapor) into liquid water. 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.
How does water cycle process takes place?
The water cycle shows the continuous movement of water within the Earth and atmosphere. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).
What are 4 properties of water?
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.
- Polarity. A water molecule is slightly charged on both ends.
- Cohesion. Hydrogen bonds hold water molecules together, as seen in the picture above.
- Adhesion.
- High Specific Heat.
What elements are present in water H2O?
To find out what water is made of, it helps to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O).
What is water chemistry?
Water Definition Water is a chemical compound consisting of two hydrogen atoms and one oxygen atom. The name water typically refers to the liquid state of the compound. The solid phase is known as ice and the gas phase is called steam. Under certain conditions, water also forms a supercritical fluid.
Where do water particles condense in atmosphere?
When a pocket of air becomes full of water vapor, clouds form. The point at which condensation starts can be easily viewed in cumulus clouds, which have flat bottoms. Those flat bottoms are where vapor begins to condense into water droplets. Clouds are simply masses of water droplets in the atmosphere.
Does evaporation takes place only at a fixed temperature?
No, evaporation does not occur at a fixed temperature. Evaporation of a liquid occurs at any temperature below its boiling point.
Where does transpiration occur in the water cycle?
The water eventually is released to the atmosphere as vapor via the plant’s stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.
Is transpiration part of the water cycle?
water cycle, also called hydrologic cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.
What are the 3 main characteristics of water?
2.2 Physical Characteristics of Water
- 1 Temperature.
- 2 Colour.
- 3 Taste and Odour.
- 4 Turbidity.
- Solids.
What are the 6 main properties of water?
The properties of water include cohesion, adhesion, capillary action, surface tension, the ability to dissolve many substances, and high specific heat. The tendency for water molecules to form weak bonds and stick to each other is called cohesion.
