What do actual vapor pressure and dew point temperature really tell us about the atmosphere?
Actual vapor pressure measures the current amount of moisture in the air, indicating how much water vapor is present compared to the maximum it can hold at a given temperature. Dew point temperature reflects the temperature at which air becomes saturated with moisture, leading to condensation. Together, these metrics provide insights into humidity levels and atmospheric stability, influencing weather patterns and comfort levels. Higher values suggest a more humid atmosphere, potentially leading to precipitation or fog.
What else can I help you with?
What is the atmospheric pressure if the temperature is at 0c the velocity of sound is 331.0ms density of air is 1.295kg and what formula is used?
Sorry, the atmospheric pressure has really nothing to do with the speed of sound at 0c, but he temperature is very important Scroll down to related links and read the short article "Speed of sound - temperature matters, not air pressure". The air pressure and the air density are proportional to each other at the same temperature.
What happens when pressure falls and temperature rises?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.
How does the pressure and temperature of each air mass cause changes?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.
What is antarctica's air pressure?
It's really not that different from the rest of the world, since it still has an entire atmosphere of air weighing down on it which is what air pressure is. If Antarctica were at sea level it would tend to be slightly higher due to high pressure prevailing (climatologically at the poles). But since much of Antarctica is up pretty high in elevation (several thousand meters) just due to there being so much ice on top of the land, the actual air pressure is pretty low - on par with that of a location in the mountains.
The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of changes in frequency. Sound waves travel at a constant speed determined by the properties of the medium they are traveling through, such as air temperature and pressure.
Does temperature affect tire pressure?
Yes, if the weather is hot - Air in the tire will expand slightly and will have an effect on the pressure as it wants to take up more room in size. If the weather is cold the air will contract and more air will be needed - the reason for the extra air is so that the tire doesn't go down. The Math: Pressure increases directly with Temperature. So there's an easy formula to use.Since 0 psig in a tire is really 14.7 psia and 0oC is really 273oK the temperature and pressure for the tires you fill is Start Pressure = (Pressure on the gauge + 14.7) psia, and Start Temperature = (Measured temp +273) . Temperature at the end = End Temperature = (Measured temp in C + 273), and pressure at the new temperature = End Pressure So: End Pressure = Start Pressure x End Temperature / Start Temperature Since End Pressure includes an extra 14.7 psia, subtract it out and that's the pressure on the gauge in psig.
How are conditions of pressure and temperature?
Temperature is particles moving really fast and bumping in to each other (in a sense, but nothing really "touches" other things atomically or else they fuse), unless of course, they are at 0 D. kelvin, and pressure is just density in the air or in another sense it's compression.
Does rubbing alcohol evaporate faster when cooled?
the atmosphere determines rate of evaporation. if the atmosphere is as dense as a liquid within the atmosphere there is no evaporation at all. on earth, cooler atmospheres are generally less dense, so it's not cooling the liquid alcohol as much as providing it with a supply of less dense atmosphere that will make a liquid, alcohol, evaporate faster. on the extreme, putting a liquid into a vacuum will cause it to almost immediately evaporate, a.k.a. standardize the temperature and pressure of its atmosphere. there is really no such thing as evaporation as much as there is homogenization, standardization, of its atmosphere.
When the temperature is constant gas volume will decrease as the pressure decreases is that true?
If I remember correctly it is a little more complicated than that. The general equation PV=nRT for an ideal gas is elementary knowledge. The fact is that when you increase temperature many things can happen. It depends on how you treat your system. In general if you increase temperature in an open system the pressure will remain fairly constant, but the volume will increase. If it is a closed system in which the volume is not allowed to expand the pressure will increase with increased temperature. You also have to remember chemical properties also such as phase changes. Hope that rambling mess helps lol.
How does sea level pressure differ from station pressure?
Station Pressure is the actual pressure the station records, however this isn't really used in meteorology as there is no comparsion due to elevation, therefore for a synoptic look, Station Pressure is converted to Sea Level Pressure.
Does the vapor pressure depend on the surrouding pressure?
No. It depends on the temperature. The only time you will really consider Pext is when you want to determine whether the substance will boil, which is when Pext = Pvap.
How do pressure cookers work and are they really much quicker?
Pressure cookers work because when you increase pressure, water boils at a higher temperature. Water normally boils at 212 degrees F. Under 15psi of pressure (standard in a pressure cooker), it boils at 257 degrees F. Since your food is cooking at a higher temperature, it will cook faster.

Is the color of the sky really blue, or is it just an illusion created by the Earth's atmosphere?
The color of the sky appears blue due to the way Earth's atmosphere scatters sunlight. It is not the actual color of the sky, but rather an optical illusion caused by the scattering of light.

What Organism can survive on Jupiter?
Probably none, considering that the temperature there oscillates arround -235°C, and that most of the atmosphere is made of hydrogen. Oh, and it rains ammonia. And there's no actual ground, it's just a huge cloud of gas. Aside for a few spores, if you're really really lucky (and even then), nothing. You'd be better to aim for one of it's moons if you wanted to send anything there.
Is color important to a painting?
not really its the actual picture that counts ! not really its the actual picture that counts !
