Dissolution Process

Dissolution Process

Dissolving Dissolving means that the solute diffuses into the solvent and mixes. It is a common case that salt or sugar is dissolved in water. Solvents are often liquid, mostly water. The…

Charle's Law

Charle’s Law

Charle’s Law Assuming constant pressure, increasing the temperature of the gas will speed up the molecular motion. As the gas often collides with the vessel wall, the volume increases. Conversely, if you…
