Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.
If the temperature of the air is said to be at absolute zero, one might conclude that a. the molecules contain a minimum amount of energy. b. the motion of the molecules is at a maximum. c. the molecules are occupying a large volume. the molecules contain a minimum amount of energy.
Best Answer: Ah Judy, there isn't such a thing as an average relative humidity. This is because it changes a lot only in the course of the day. How much moisture the air can contain depends on the temperature. The warmer it is, the more moisture it can contain. That is the absolute humidity that is the volume of water per volume of air. The relative humidity, which is what you measure with a hygrometer, is the percentage of moisture to achieve full saturation for a given temperature. But since the temperature varies a lot during the course of a day, so does the relative humidity.
