Longitudinal Waves. To see a animations of spherical longitudinal waves check out: In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The animation at right shows a one-dimensional longitudinal plane wave propagating down a tube.
The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
Jun 29, 2014. Increasing the temperature usually increases the rate of formation and the solubility of solids and liquids, but it decreases the solubility of gases. SOLIDS AND LIQUIDS. For many solids dissolved in liquid water, the solubility increases with temperature.
