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.
Absolute humidity is the total mass of water vapor present in a given volume of air. It does not take temperature into consideration. Absolute humidity in the atmosphere ranges from near zero to roughly 30 grams per cubic meter when the air is saturated at 30 Â°C.he relative humidity of an air-water mixture is defined as the ratio of the partial pressure of water vapor (H 2 O) in the mixture to the saturated vapor pressure of water at a given temperature. Thus the relative humidity of air is a function of both water content and temperature.
