What else can I help you with?
Why can a carefully placed needle float on water even though it is more dense then the water?
Because of the surface tension: the attracting force between the water molecules, which effectively causes a "skin" on the top of the water. Drop a few drops of soap in the water and the needle will sink, because the soap weakens the bond between the water's molecules.
What factors contribute to the limited solubility of sparingly soluble substances in aqueous solutions?
The limited solubility of sparingly soluble substances in aqueous solutions is primarily due to the strong attraction between the particles of the substance and the water molecules. This attraction makes it difficult for the substance to dissolve fully in water, resulting in limited solubility. Other factors that contribute to limited solubility include the size and structure of the molecules, as well as the presence of other ions or molecules in the solution that can interfere with the dissolution process.
What are the basic principles of sonoluminessence?
Soundwaves are run through a bubble in water which causes the bubble to violently collapse. As the gas molecules collide at high speeds, heat and light energy is given off.
How are the molecules arranged in liquid water?
molecules in water are all different sizes and don't really have a arrange meant
What causes conservation?
causes of water arerunning taps,daily uses of washing machines,use of drinking water for washing cars or cleaning floors,construction/repair work.gardening,farming etc r the main causes of wastage of water.....
Is adhesion responsible for the attraction between water molecules and the glass sides of a graduated cylinder?
Yes, adhesion is responsible for the attraction between water molecules and the glass sides of a graduated cylinder. Adhesion is the force of attraction between different molecules, in this case, water molecules and the glass molecules. This attraction causes the water to stick to the glass surface instead of forming a perfect dome shape.
In water can you say the attraction between H2 and Ois Adhesion and H2O and H2O is Cohesion?
No, in water, the attraction between H2 and O is a covalent bond that forms the water molecule. Adhesion refers to the attraction between different molecules, while cohesion refers to the attraction between the same molecules. In water, the attraction between H2O molecules is cohesion, and the attraction between water molecules and other substances is adhesion.
What is the attraction that causes water molecules to stick togeather called?
cohesion
What is the cause of the attraction between molecules of water?
Polar water molecules are associated by hydrogen bonds.
Is water to water an example of whesion or adhesion?
Water to water is an example of cohesion, which refers to the attraction between molecules of the same substance. Adhesion, on the other hand, is the attraction between molecules of different substances.
What force of attraction is responsible for the formation of a thin film on the surface of water?
The attraction that causes water and other liquids to form drops and thin films is cohesion. The attraction between oppositely charges ions results in the formation of an ionic bond.
The attraction of water molecules to other molecules is called?
Water molecules attract the opposite poles of other polar molecules through poles present in water itself.
Cohesion and adhesion are?
Information used from Prentice Hall Biology book from the year 2006. Cohesion is the attraction between molecules of the same substance. Due to hydrogen bonding water is very cohesive. Water's cohesion causes molecules on the surface of the water to be drawn inward causing "surface tension". This property allows insects to walk on water. Adhesion is the attraction between molecules of different substances. Adhesion causes water to rise in a narrow tube against the force of gravity for example the forces that draw water out of the roots of the plants and up into its stems and leaves, this is called capillarity.
Cohesion describes the attraction between a water molecule and another type of polar molecule?
Cohesion refers to the attraction between molecules of the same substance, like water molecules sticking to each other. Adhesion, on the other hand, is the attraction between molecules of different substances, such as water molecules sticking to a polar molecule like glass.
Difference between adhesion and cohesion?
Adhesion is the intermolecular attraction between 'unlike-molecules' (usually referred to the attraction or joining of two different objects of fluids to each other).Cohesion is the intermolecular attraction between 'like-molecules' (usually referred to the strength with which the particles of an object of fluid attract to each other)
What is the attraction between water molecules and the molecules of solid surfaces called?
The attraction between water molecules and solid surfaces is called adhesion. This phenomenon is due to the intermolecular forces between the molecules involved, leading to the water molecules being attracted to the surface of the solid.
What bonds are on the weak side of chemical attraction between water molecules?
hydrogen
