Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more …

The structure of water molecules and how they can interact to form hydrogen bonds.

Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one …

It could be a whole set of molecules, but water in most biological or chemical systems tends to be the most typical solvent. It's what other things are dissolved into.

If you talk under water, it sounds funny because the water is carrying the sound wave instead of air. Water is a liquid and air is a gas, so water is much denser than air, and the particles are …

The number of water molecules is so high, that their individual random paths average out. This is why diffusion tends to keep the quantities of water on both sides equal.

Water interacts differently with charged and polar substances than with nonpolar substances because of the polarity of its own molecules. Water molecules are polar, with partial positive …

Learn about the three main states of matter and how particles behave differently in solids, liquids, and gases. Discover what happens during phase changes like melting and boiling and how …

In a laboratory experiment, water moves across a selectively permeable barrier from an area of lower solute concentration to an area of higher solute concentration, demonstrating osmosis.

If a cell is placed in a hypertonic solution, water will be attracted to the environment and leave the cell, and the cell will shrink. In an isotonic environment, there is the same amount of water on …
