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.
A relative humidity of 100% means the air cannot contain any more water vapor at that temperature, whereas a relative humidity of 50% means that the air only has only half as much water vapor as it can hold at the current temperature.Dew Point is the air temperature at which the air is saturated with water vapor.Warm air can âholdâ more water than cold air. When air at a given temperature canât hold any more water it is fully saturated and is at 100% relative humidity. The air isnât holding onto the water vapor.hese limit how much drying occurs. If your shop is at 100% relative humidity it doesnât matter how long you âdryâ the concrete. It wonât lose moisture and dry out because the air surrounding the concrete canât hold any more moisture. Remember: wet concrete doesnât dry out in small, cold shops with still air.
