When a vapor or liquid in a closed environment reaches an equilibrium between the amount of evaporating, condensing and returning molecules, the liquid or vapor is saturated. Saturated vapor is also known as dry vapor. More »

Water has a low vapor pressure due to the strong intermolecular forces between its molecules. The type of chemical bonding between water molecules is referred to as hydrogen bonding. More »

The chemical formula for water vapor is H2O. Water is a unique compound because it has the ability to exist on the earth's surface in all three forms: liquid, solid (ice), and gas (water vapor). More »

The process of a gas changing to a liquid is called condensation, and for condensation to take place, the environment has to reach maximum vapor pressure, generally through a lowering of temperature in the case of the wa... More »

Sugar is able to melt ice because it disrupts the equilibrium of the water molecules and causes the freezing process to slow down, resulting in conditions that favor the melting process over the freezing process. The add... More »

Henry's law, formulated by chemist William Henry in 1803, states, "at a constant temperature, the amount of a given gas that dissolves in a liquid is directly proportional to the partial pressure of that gas in equilibri... More »

The changing of a liquid into a vapor is known as evaporation. This process requires a certain level of energy, often in the form of heat, to take place. More »
