What happens to the air in the nasal cavity?
What are the four major types of air masses according to moisture content?
Precipitation
What is sensible heat without moisture?
Sensible heat is the heat required to raise the temperature of a substance. When determining the heat of a vapor, moisture must be considered as it removes heat from the vapor (in order to heat the moisture [water vapor] to the ambient temperature). Dry steam has no moisture. Dry air has no moisture (a physical improbability). Air normally has moisture determined as relative humidity. This humidity [water vapor] must be heated with the air. Then the moisture heat absorption must be subtracted from the whole to determine the heat absorption of the air without moisture, expressed as heat per unit per degree (often 0.24 btu per dry standard cubic foot per degree F for air). Any moisture in the air increases the heat necessary to raise the temperature by about 1 btu per pound of moisture per degree F. (0.004 btu per gram of moisture per degree F). This increased heat requirement becomes more evident as air is compressed, and the moisture is removed by condensation.
How is moisture content and temperature of an air mass determined?
By The source region
Why does an updraft within a thundercloud tend to rise higher if the air has a higher moisture content?
The moisture content is not the only factor. it has to do with the temperature of the air. WARM AIR RISES, Cool air falls. the air in the updraft is warmer than the air around it. The greater difference in temp means faster and greater updrafts
What happens to air's moisture and heat content?
they died dn
As an air mass moves first upslope and then downslope over a mountain. What happens to air's moisture and heat content?
look in ch. 31 of your textbook
What happens to the air in the nasal cavity?
What instruments measure air moisture?
A hygrometer measures the moisture content of the air. There are several different types, all of which measure something else which indicates the moisture content.
Temperature in the air is increased by the process of moisture condensation?
Yes, temperature in the air has more moisture content . Due to the condensation of particles in the humidity liberates the particle which has high heat particles which increases the temperature.
What 2 factors speed up evaporation?
Heat, altitude, and moisture content in the air are factors which may effect the speed of evaporation.
When air passes through a cooling coil what is the effect on its moisture content?
definitely, when air passes thruogh a cooling coil then moisture content of the air is increase b'coz condensation take place...
What are the four major types of air masses according to moisture content?
Precipitation
Air masses are identified on the basis of temperature and what?
moisture content
What is the art of measuring moisture content of air called?
psychrometry

Why is it important to know the moisture content in air entering the boiler?
Since water does not burn, any moisture in the combustion air will simply be heated by the fire. Since water has a large heat capacity, this results in wasted energy. The drier the combustion air the more efficiently the burner will burn.
