The force of gravity; not the attraction of the Earth for all matter on it, but the same force that attracts all matter to all other matter.
cohesion is the answer
The intermolecular forces between water molecules are lowered at the water surface and some molecules escape in the atmosphere. Evaporation is increased by temperature.
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.
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.
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.
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.
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.
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.
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.
Hydrogen bonds are formed between water and ethanol molecules, the solution become more "packed"; the density increase and the volume decrease.
what causes water molecules to be attracteed to one another
The attractive force that exists between water molecules and causes them to stick together is called hydrogen bonding. This occurs due to the polar nature of water, where the positive hydrogen atoms are attracted to the negative oxygen atoms of nearby water molecules. Hydrogen bonding is responsible for many unique properties of water, including its high surface tension and cohesion.
