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.

The changes of matter from a gas state to a liquid state?
It's called liquifying, or condensing. Water vapor in the atmosphere condenses into tiny droplets of water which scatter light, and collections of these are called clouds.
When temperature increases and humidity of air decreases the fog dissipates. Answer, Fog is moisture in the air condensing due to cooler ambient temperature at ground level. As the ambient temperature increases, generally due to the sun, the moisture in the fog will burn off and the fog will lift. You can't see vapor, but you can see droplets of water, droplets small enough to float in air (brownian motion). Whenever the droplets evaporate (heat, low humidity, etc) the water doesn't go anywhere but now you can see through it, thus "no fog".
What is the difference between water vapor molecules and liquid water molecules?
They are made of different states of matter
Which phase change is an exothermic process?
Change of phase from gas to liquid to solid are exothermic reaction. Condensation, deposition and freezing are exothermic processes that undergo change in phase.
How do jet streams affect air masses?
When an air mass moves into an area and interacts with other air masses, it causes the weather to change. In the continental United States, air masses are commonly moved by the prevailing westerlies and jet streams.
Solids that will form a suspension in water?
Does the mixture of potassium sulphate and water form a suspension
Is fog an clouds part of the atmosphere?
Yes, but they are clouds that are not high up in the sky. They are low clouds!
What happens to air pressure when water vapor increases?
Atmospheric pressure is reduced with increasing water vapor because the water has a lower molecular weight than dry air. The same number of molecules occupy a given volume at a given pressure, so the total mass of water vapor laden air is lower than dry air. If you add up the weight of a column of the wet air it will weigh less than the same column filled with dry air, hence, wet air has a lower air pressure.
Cirrus clouds form at high altitudes and appear thin and wispy. They are composed of ice crystals and do not typically produce precipitation.
A brief discussion of the operating vapor-compression cycle is helpful to indicate other potential refrigeration problems in real systems. In the basic cycle, slightly subcooled refrigerant leaves the condenser at high pressure and flows into the liquid receiver if one is present. The refrigerant then enters the throttling device (capillary tube, TXV, etc.) where the pressure is dropped. It then enters the evaporator as a two-phase mixture (liquid and vapor) and evaporates or boils at low temperature, adsorbing heat. Slightly superheated refrigerant vapor exits the evaporator and enters the suction line accumulator, if one is present (used to trap any transient liquid slugs). The refrigerant vapor then enters the compressor where the pressure and temperature are increased as the compressor compresses the refrigerant vapor. The vapor leaving the compressor is superheated, and the compressor discharge is the hottest point in the cycle. This refrigerant is cooled and condensed in the condenser where heat is rejected, and the refrigerant is condensed to liquid. Refrigerant actually leaves the condenser slightly subcooled (subcooled liquid) to assure condensation has been complete. Any non-condensable vapors in the system will be unable to condense in the condenser and will appear as gas bubbles in the condensed liquid stream. These non-condensables may collect in the condenser and displace refrigerant from the condenser heat exchanger, thereby reducing the effective surface area of the condenser.
The compressor changes the low pressure vapor to high pressure vapor sending it threw the condenser to cool and turn it back into liquid.
When liquid water changes into steam what is it called?
Vaporization is the phase transition that takes place when liquid water turns to steam. The type of vaporization that occurs in this case is boiling.
What is nuts and bolts a solid a liquid or a gas?
Nuts and bolts are solid cylinders with the head. Many companies manufacture nuts and bolts for supplying to other industrial firms. In every construction and industrial work, nuts and bolts are usable. To get more detail about the process and to make deal with a reputed company, contact Mig Enterprises, Fasteners Supplier Sydney.
When air moves from an area of low pressure it causes?
When air moves from an area of low pressure, it causes wind to blow towards the area of higher pressure. This movement of air creates atmospheric circulation patterns that help balance out pressure differences in the atmosphere.
Is cirrus the root word that tells us a cloud brings rain?
No, "cirrus" is a type of high-altitude cloud, typically wispy and feathery in appearance, but it does not specifically indicate that rain is coming. Clouds that bring rain are generally associated with nimbus or cumulus clouds. Each type of cloud has its own characteristics and weather implications.
Can clouds move across the sky if wind is not blowing?
The majority of wind orginates from one or both of two sources: clouds and trees. As the clouds move, they push the air, creating wind. The relation is linear: the faster the clouds, the faster the wind. Trees also contribute to wind, especially at ground level. Trees sway back and forth and their leaves catch the air and 'throw' wind currents. The more frenetically a tree sways, the greater the wind. A tree that sways so violently that it falls over can create gusts of wind up to 120mph!
There are many other sources lesser of wind, some natural (e.g. waves) and some man-made (e.g. windmills and sailboats).
What are the 4 steps that clouds form?
Clouds can form in one of four ways: mountains, the rise of air masses, cold or warm weather fronts, and surface heating. Cumulus clouds form by surface heating or mountains, status forms by weather fronts, and all types can form by the rising of air masses.
What are white puffy clouds with flat bottoms called?
The clouds that are puffy masses formed by vertically rising air are commonly known as thunderheads. These clouds, with the scientific name of cumulonimbus, may produce severe weather such as lightning, hail, and even tornadoes.
What has the change is a state of matter from a liquid to a gas?
sublimation is the process in which a solid directly gets converted into a gas. example:camphor, naphthalene
Why is flour a solid and not a liquid or gas?
Flour acts as a solid when in a stationary state however if air is blown into the flour at a calculated rate, the flour can take on the properties of a liquid. Adding air to the flour adds energy which moves the particles similar to adding energy to a block of ice which excites the molecules into movement.
Does air flow from areas of higher pressure to areas of lower pressure?
Air will flow from areas of high pressure to areas of low pressure.
Pressure = force/area.
So in this context, air pressure is the force the particles in that area exert on the space around them (let's imagine they're in a box). As air particles whizz around, they will collide with the edges of the box, so bouncing off and changing direction. This direction change involves a lot of acceleration (though speed may be the same, velocity (which is speed in a specific DIRECTION) will be very different.
Physics tells us F=MA. Therefore, this acceleration will equate to a force on the outside world. This force will therefore be proportional to the number of particles in the area (more particles = more area).
So, if an area of high pressure has lots of particles, there will be a spreading out of these particles to areas of low particles (diffusion, and energy's natural tendency to spread out). Alternatively, think of it as particles in the high pressure area pushing against the particles from the low area, and they're pushing force being greater, so they win!
There you have a very long winded answer for why air moves from high pressure to low pressure!

Why is the troposphere important to meteorologists?
The troposphere is the lowest layer of earth's atmosphere. its in this layer that all claimatic changes take place.
What do you call a cloud of dust particles where a star is born?
It is called a Nebula (nebulae for plural).
no sorry but your wrong it is a coma
It can be both it just depends. The question needs to be more specific
Let us assume we have all our data in Oracle RDBMS database. Now we decide to move our data from Oracle Database to Microsoft SQL Server database. The porting of data from RDBMS to another RDBMS is called Migration.
