What property of water causes the curved surface?
Adhesion
How does water as a solvent support life?
Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
What is the example of anomalous Behaviour of water?
Answer. water has a unique property of anomalous expansion. When water is cooled from room temperature it first contracts in volume and becomes increasingly dense as do other liquids, but at 4° C water reaches its maximum density. On further cooling it starts expanding and become less dense.
Is an example of anomalous?
The definition of anomalous is something abnormal or deviating from the usual method. A person with 50 piercings and tattoos is an example of someone who is anomalous. Deviating from the normal or common order, form, or rule.
What is the importance of anomalous Behaviour of water?
The anomalous expansion of water helps preserve aquatic life during very cold weather. When temperature falls, the top layer of water in a pond contracts, becomes denser and sinks to the bottom. A circulation is thus set up until the entire water in the pond reaches its maximum density at 4°C.
What is this Behaviour of water called?
The anomalous behavior of water, sometimes called the density anomaly, is due to strong intermolecular attractions between water molecules called hydrogen bonds. The large electronegativity difference between oxygen and hydrogen causes the hydrogen-oxygen bonds to be polar.
What is the unusual Behaviour of water?
Besides mercury, water has the highest surface tension for all liquids. Water’s high surface tension is due to the hydrogen bonding in water molecules. Water also has an exceptionally high heat of vaporization. Vaporization occurs when a liquid changes to a gas, which makes it an endothermic reaction.
What is the reason of anomalous Behaviour?
Reasons for Anomalous Periodic Properties Small size of these atoms. High electronegativity. Large charge/radius ratio.
What is used to study the anomalous Behaviour of water?
Hope’s apparatus
What is the importance anomalous Behaviour?
when a student want to make an experiment on water boiling point,when water its placed in a barrel and placed on fire,these anomalous particles of water vibrates evenly making convectional current movement of water thus enabling it to reach at the maximum boiling point.
What is the importance anomalous?
Answer. Anomalous refer to the small particles which are present in liquid for instance in water. They are quite closely packed together. If one were to conduct an experiment to showcase the density of water then they would understand how the density of water actually increases when there is a rise in the temperature.
What is the meaning of anomalous Behaviour?
Anomalous behavior is a behavior that is different from its original order. It shows different properties from other members of its groups. Elements that show anomalous behavior have unique properties and form different compounds.
What is the reason behind the anomalous expansion of water?
Explanation: Due to anomalous expansion of water between a temperature range of 0oC to 4oC, it contracts, i.e., water molecules come closer and hence its volume decreases. On further heating, it starts to expand (molecules get farther from each other) and the volume increases.
