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.
Yes Generally, the melting point of a substance increases as the pressure increases. There are some notable exceptions, however, water being one.Yes, but... Yes, it does have an effect, but it is a small one (not nearly as large as the effect on boiling points for instance).es, generally as pressure increases the melting point increases. The only exception to this is water, for which the opposite is true: increased pressure lowers the melting â¦ point.
