Why humid air is lighter than dry air?
Because water vapor is relatively light compared to O2 and N2, the mass of humid air is less per unit volume than of dry air. This makes humid air less dense and causes the buoyant force on it making it rise in dry air.
Is humid air heavier than dry air?
Yes, humid air is heavier than dry air because water vapor molecules in humid air add to its overall weight.
Is there less oxygen in humid air compared to dry air?
Yes, there is less oxygen in humid air compared to dry air.
What is the mass in grams in 1.00 molar mass FE?
What is the chemical 'FE'. Do you mean 'Fe'. If so to answer your question . The molar mass of iron (Fe) is 55.845
Does humid air rise or sink in the atmosphere?
Humid air rises in the atmosphere because it is less dense than dry air.
What type of air mass is humid and warm?
A warm air mass which would be cyclonic.
What is a tropical air mass?
Warm, humid
What is maritime tropical air mass like?
The maritime tropical air mass is warm and humid.
What are the characteristics of a tropical air mass?
Warm and humid(:
What is the name for a warm and humid air mass that forms over an ocean?
Air masses with those characteristics are termed "maritime tropical".
How does humid affect sound?
The speed that sound waves propagate through a gas follows the equation: v = sqrt(gamma*R*T)/M), where gamma is the adiabatic index, which, for air, is about 1.4, and is barely (if at all (I'm no expert, just a physics major)) related to the density of air. R is the Universal Gas Constant (~8.31 J/(mol*K)), T is temperature (K), and M is the molecular weight (kg/mol). Humid air is actually less dense than dry air. This is due to the fact that dry air is primarily composed of N2 and O2 molecules, which have a molecular mass of around 28 and 32 Atomic Mass units, respectively. A molecule of water has a mass of only 18 atomic mass units. Therefore, a mole of dry air molecules weighs more than a mole of relatively humid air molecules. Because the molar mass (M) is less for humid air, the denominator inside of the above-mentioned velocity function is reduced, and the numerator effectively stays constant. Therefore, the fraction becomes larger, and the speed of sound increases as molar mass decreases. The amplitude of sound waves stays larger for longer in humid air. This is because energy is needed in order to move the molecules in the air and propagate the sound. Less dense air (humid air) has less mass to be moved in order to propagate the sound, and therefore less energy goes into propagating the sound and more energy can remain in the form of the amplitude of the wave. Summary: The speed of sound waves and the amplitude of sound waves through humid air is greater because humid air is actually less dense than dry air.
A humid air mass that forms over oceans?
maritime
Which air mass would cause a hot humid spell in the northeastern US during?
A warm, moist air mass from the Gulf of Mexico, known as a maritime tropical air mass, would likely cause a hot and humid spell in the northeastern US during summer. This air mass brings warm and humid conditions, leading to high temperatures and high levels of humidity.
Is a maritime tropical air mass warm and humid or dry?
dry
What kind of air mass causes hot humid weather?
A tropical air mass typically causes hot and humid weather. This air mass forms over warm tropical regions and carries high levels of heat and moisture, leading to sultry and sticky conditions when it moves into an area.
What effect does warm dry air mass have on the area over which it moves?
A warm and dry air mass can make the area over which it moves arid and less humid. This is why deserts have dry air while coastal areas are humid.
Why humid air is lighter than dry air?
Because water vapor is relatively light compared to O2 and N2, the mass of humid air is less per unit volume than of dry air. This makes humid air less dense and causes the buoyant force on it making it rise in dry air.
