Document Summary
In part, water sustains life through its ability to dissolve other. The macroscopic properties of substances, which we can readily substances. Water is sometimes called nature"s solvent because ionic and molecular solids, other liquids, and atmospheric gases all dissolve in it, at least a little. 6. 1 london dispersion forces: they"re everywhere observe and measure, arise from the microscopic interactions between the particles that make up those substances. The particles in liquids (and solids) are in direct contact with each other. However, when a liquid vaporizes, the contacts are broken: the gas-phase particles become essentially free and independent. Separating liquid-phase particles that are attracted to each other takes energy, and the stronger the particles attraction for each other, the greater the energy needed to separate them. Greater energy requirements mean higher boiling points. similar to the electrostatic interactions involved in covalent bond formation.
