Which of the following properties of water allows water to climb up a tube?
Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to right) is limited by surface tension and, of course, gravity.
How does water move up the thin walls of a tube specifically what is it sticking to?
Water molecules are attracted to one another by a force called cohesion. The tendency of water to rise in a thin tube is called capillary action. Water is attracted to the walls of the tube, and the water molecules are attracted to each other. The thinner the tube, the higher the water will rise inside it.
Which of the following properties of water allows an insect to climb up a tube density capillary action cohesion adhesion?
Explanation: The capillary action of the water allows it to climb up the trees. The capillary action is the phenomenon seen in the water or other liquids that allows it to move through a tube.
Which of the following properties of water allows an insect to walk on water?
Which of the following describes surface tension in water?
Surface tension could be defined as the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of the water molecules.
Which of the following is an example of phenomenon of surface tension?
Surface tension, property of a liquid surface displayed by its acting as if it were a stretched elastic membrane. This phenomenon can be observed in the nearly spherical shape of small drops of liquids and of soap bubbles. Because of this property, certain insects can stand on the surface of water.
What is surface tension describe how surface tension in water is useful for plants and animals?
surface tension of water helps creatures(mostly of insecta class such as water striders) to walk on water. . it also helps water to move up the xylem tissue of higher plants without breaking up.
Which of the following is an application of surface tension?
Explanation: Use of soaps and detergents as cleansing agents, molecular structure can be elucidated by surface tension measurements through parachor values and surfactants are incorporated in preparations like toothpaste are the applications of surface tension.
What are the clinical applications of surface tension?
In medicine, surface tension measurement is above all used in connection with various pathological states of lung surfactants such as adult respiratory distress syndrome, bronchial asthma, and pneumonia.
What are the factors affecting surface tension?
As temperature decreases, surface tension increases. Conversely, as surface tension decreases strong; as molecules become more active with an increase in temperature becoming zero at its boiling point and vanishing at critical temperature. Adding chemicals to a liquid will change its surface tension characteristics.
How can surface tension be used in real life?
The effects of surface tension are of central importance in many everyday phenomena: it causes small droplets of rain to stick to your windows, creates bubbles when you add detergent in your sink, and propels water-striding insects on the surface of ponds.
What would happen if there was no surface tension?
If the world didn’t really have surface tension, there also wouldn’t be hydrogen bonding; which is what makes liquid, liquid. If surface tension wasn’t in our body all the acids, blood, saliva, yes even pee and every other liquid in our body would mix together, in turn, we would die.
What would happen if water has weak surface tension?
What do you predict would happen if water had weak surface tension? Plants would not be able to draw water from the ground through their roots. Water molecules would attract each other. Water would only be able to dissolve nonpolar substances.
What has the most surface tension?
What liquid has the strongest surface tension?
What liquid has the least surface tension?
In which substances would you expect to see greater surface tension Why?
Liquids that have strong intermolecular forces, like the hydrogen bonding in water, exhibit the greatest surface tension. Surface tension allows objects that are denser than water, such as the paper clip shown in B in Figure below , to nonetheless float on its surface.
Does water purity affect surface tension?
This is because plain tap water has higher surface tension, so the surface is “stronger” and can hold together a larger drop. Adding soap lowers the water’s surface tension so the drop becomes weaker and breaks apart sooner.
Do other liquids have surface tension?
Because of the relatively high attraction of water molecules to each other through a web of hydrogen bonds, water has a higher surface tension (72.8 millinewtons (mN) per meter at 20 °C) than most other liquids….Contact angles.
|Some liquid–solid contact angles|
What is the difference between surface tension and surface energy?
The attractive force of the molecules present at the surface of a liquid towards each other is called the surface tension of that liquid. Surface energy is the equivalent attractive force present between the molecules at the surface of a solid substance.
How does the surface tension of water compare to the surface tension of other liquids?
How does the surface tension of water compare with the surface tensions of most other liquids? It is higher. What is the shape of the water molecule?
Why does water have high surface tension but low viscosity?
Water’s high surface tension is due to the hydrogen bonding in water molecules. Water has very strong intermolecular forces, hence the low vapor pressure, but it’s even lower compared to larger molecules with low vapor pressures. Viscosity is the property of fluid having high resistance to flow.
Which liquid has highest viscosity?
Liquids which flow very slowly, like glycerin or honey, have high viscosities. Those like ether or gasoline which flow very readily have low viscosities. Viscosity is governed by the strength of intermolecular forces and especially by the shapes of the molecules of a liquid.
Does higher viscosity mean higher surface tension?
If you relate the water and syrup demonstration you will see that a higher viscosity means a greater surface tension and a lower viscosity means a lower surface tension.
How do you explain the fact that water has the highest surface tension but the lowest viscosity?
How do you explain the fact that water has the highest surface tension but the lowest viscosity? Water molecules at the surface of a drop are missing a few hydrogen bonds and are strongly pulled into the center of the drop, resulting in high surface tension.
