What causes the attraction between water molecules causes?
cohesion is the answer
What causes of the water to evaporate?
The intermolecular forces between water molecules are lowered at the water surface and some molecules escape in the atmosphere. Evaporation is increased by temperature.
What property causes water to form droplets?
Surface tension is the property that causes water to form droplets. The cohesive forces between water molecules at the surface of the droplet are stronger than the adhesive forces between the water and the surface it is on, causing the water molecules to form a spherical shape.
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.
When alcohol dissolved in water why temperature of alcohol is increased?
The hydrogen bonds between water molecules and respectively hydrogen bonds between ethanol molecules are broken by mixing; new hydrogen bonds are formed between water and ethanol molecules - this second process is exothermic.
Why does a concave meniscus form when water is in a graduated cylinder?
A concave meniscus forms in a graduated cylinder with water due to adhesive forces between the water molecules and the walls of the cylinder. This causes the water to cling to the walls, resulting in a concave shape.
Why oil molecules are not attracted to water molecules in vinegar?
Oil molecules are nonpolar and hydrophobic, meaning they do not have an affinity for water molecules which are polar. This difference in polarity causes oil and water to be immiscible, leading to the separation between the two substances in vinegar.
How water acts as a lubricant and transport facilitator?
The polarity of the water molecule, which causes hydrogen bonds to form between the water molecules, is the characteristic that enables it to act as a lubricant.
What causes sugar to disperse evenly in water?
When sugar is added to water, the water molecules surround the sugar molecules and disrupt the attractive forces between sugar molecules, causing them to separate and disperse evenly throughout the water. This process is known as dissolution or dissolving, and it occurs because water is a polar molecule that can interact with the polar sugar molecules.
What causes volume contraction between ethanol and water?
Hydrogen bonds are formed between water and ethanol molecules, the solution become more "packed"; the density increase and the volume decrease.
What causes water molecule to be attracted to one on another?
what causes water molecules to be attracteed to one another
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.
