Clouds
A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes up to several miles above sea level. They are generally produced by the condensation of water vapor. Other clouds, less commonly seen, are composed of smokes or dusts.

Does warm air have less molecules than cool air?
If they are both under the same pressure and are the same in volume, then, yes, warm air has fewer molecules
Within a low-pressure system the probability of precipitation is high because the air is generally?
Within a low-pressure system, the air is rising and cooling, leading to the condensation of water vapor into clouds and eventually precipitation. This process is driven by the low pressure causing air parcels to rise and cool, increasing the likelihood of precipitation.
What is the last step in the order of operations?
Subtraction. Remeber it's PEMDAS. Parenthesis, Exponent, Multiplication, Division, Addition and Subtraction.
The car has dual AC systems, you would have to check if the left side AC has a fuse burnt out or some sort.
Had the same problem and found to have a leak on passenger side of system. Shop charged $186.00 to recharge and replace valves and repair leak. blowing cold every since.
Suggest an activity to show that air contains moisture?
An activity to demonstrate that air contains moisture is to use a mirror. Hold a mirror up to your mouth and breathe on it. The moisture in your breath will condense on the mirror, showing that the air you exhaled contained moisture.
What are the step to get a support order corrected if submitted incorrectly?
Contact the clerk of the court where the order was filed and they can inform you of the proper procedure to amend the petition.
What are the symbols for fronts high air pressures low pressures and hurricanes on a weather map?
High pressure is represented by a blue letter "H" while low pressure is represented by a red "L." Hurricanes are represented by circles with spiral arms.
What do water molecules lose when evaporating?
Water molecules loose its state. It gets converted into vapors.
What causes a Ford Windstar to all of a sudden blow cold air instead of warm?

Answer
If you have the heater on and the fan is blowing warm or hot air and then changes to cold, you possibly have air in the circulation lines from the radiator to the heater core. As the water pumps pumps the water through then engine and then heats it up it goes to your heater core under your dash to provide you with heat. If there are air gaps in the system, the water pump will push the water through and then the air trapped and you will end up with cold or cool air. I suggest you check your antifreeze level WHEN IT'S COLD and see if you are low. If so, add antifreeze and run the engine at idle to get the antifreeze to circulate through the system leaving the radiator cap off while you are doing this. Hopefully as the water gets circulated around the air will come to the top of the radiaotr and escape, add more antifreeze and top off your radiator. Any excess fluid should go to your overflow tank. Some engines requires you open certain passages to release the trapped air but you could try this first

What causes the AC in a 1999 Ford Escort to blow warm air?
If the compressor is not turning on it could be as simple as low refrigerant level. If the compressor IS turning on, it might be a stuck heater core valve.
Why would water pressure in the whole house suddenly drop Can't find an obvious leak anywhere.?
A leak probably wouldn't cause a "sudden" drop in pressure. It sounds more like the system has more users than it can supply and pressure drops when someone else turns on their shower or flushes their toilet.
The lapse rate for moist air is lower than for dry air because?
- Moist air has water vapor in it.
- As a moist air parcel rises, the water vapor will condense (latent heat of condensation)
- latent heat is released, meaning a temperature increase occurs within that air parcel, effectively dampening its lapse rate.
Thus, the latent heat of condensation is working to decrease the lapse rate because sensible heat is being released in the process; its called the Moist Adiabatic Rate (MAR)
In contrast, the Dry Adiabatic Rate (DAR) considered for Dry air (no water vapor) does not involve condensation, and thus no latent heat is released; meaning the lapse rate is unaffected.
What will the weather be like when air pressure is rising?
When air pressure is rising, it means that a high pressure area is coming in your direction. High pressure areas tend to bring very sunny and calm weather so the weather should improve when the air pressure is rising
What has forced some comets that originated in the kuiper belt outward into the Oort cloud?
Gravitational interactions between passing objects always has the potential to disturb the orbits of the two bodies involved, but I'm unaware of any research indicating that objects have been observed to have been perturbed OUTWARD from the Kuiper Belt to the far more distant (and hypothetical) Oort Cloud. It has probably happened, at least a FEW times. But the Kuiper Belt itself is so distant that our ability to detect comet-sized objects is quite limited. And aside from the philosophical argument of "Where do new comets come from, if not from the Oort cloud?", we have precisely ZERO actual evidence that the Oort Cloud exists as postulated.
There have been intermittent speculations that a massive but dark object, perhaps a planet or a brown dwarf star, might be in a highly elliptical orbit around the Sun. This object, occasionally named "Nemesis", might perturb distant Oort Cloud and Kuiper Belt objects out of their lazy orbits and drop them into the inner solar system as comets. The idea is that this might explain some strange periodicity of mass extinctions on Earth, that we might expect at any century a withering cosmic hailstorm of deadly proportion.
But the proposed math and timetables never seems to work out, and a massive enough object should have been discovered by now.
Oort cloud comets are so far from the Sun that gravity of neighboring stars can alter their orbits?
True. We think; the Oort Cloud is a hypothesis, because so far we are unable to detect small dark objects so far from the Earth. We have never actually detected anything in the Oort Cloud. But long-period comets come from SOMEWHERE, and Jan Oort's idea of a "cloud" of primitive objects makes sense.
What should the high low pressure for the AC be when running?
Depends on the ambient temperature - need a chart for details
Dry air exerts less pressure than air that has?
Dry air exerts less pressure than air that has a higher humidity. In general, air pressure is the sum of the individual pressures of gases present in the air. Dry air lacks any water vapor pressure in the air. Therefore, any air with a humidity above 0% has a higher pressure than dry air.
