Question

So wha t is the real meaning of evaporatoin and condences?

Answer 1

Cheezee. Good answer and very clear. Chemically acceptable.

J_Maverick. What!!! U have had 2 years of chemistry and you were confusing even me. You need a review of chemistry and clear explanation!

Answer 2

the expansion and concentration of materials through change in temperature or pressure

Answer 3

Evaporation is water when "goes into thin air."

Condensation is water "comes down from the air." <}:-})

Answer 4

Evaporation is when liquid particles become heated up and begin to move faster. When they move faster, they tend to jump out of their liquid. Thus becoming gas.

Condensation is when gas particles become colder and slow down. Then they become a liquid. Basically the opposite of evaporation.

Answer 5

evaportaion-it is when the water particuls turn really fast bouncing all over the place and escape through a gas form.

condensation-is when like for example for a car and its winter inside is really warm, out side is cold so on the window the warm air will hit the cold and turn into water which is on the window

Answer 6

Well,its a part of the water cycle.whats there to not understand?evaparation is a liquid water changes to water vapor...and condensation is,a process which water vapor turns into liquid water.

Answer 7

Condensation is gas->liquid becuase of changes in pressure or temperature.  What is being condensed affects what pressure or temperature (or combination thereof) is required to make the phase change.  Evaporation is liquid->gas becuase of changes in pressure or temperature.  Again, what is being evaporated affects how much the temperature and/or pressure must change.  Plotting all the phase changes as points on a graph where the y axis is pressure and the x is temperature gives you a vaguely Y shape.  This graph is called a phase diagram.  You can use it to figure out what state the element that is being graphed will be in at a temp./pressure combination.  You can also use it to answer questions like "How much must the temperature decrease to cause this element to melt at ____ pressure?"

Answer 8

Evaporation is the process by which molecules in a liquid state (e.g. water) spontaneously become gaseous (e.g. water vapor). It is the opposite of condensation. Generally, evaporation can be seen by the gradual disappearance of a liquid, when exposed to a significant volume of gas.

On average, the molecules do not have enough energy to escape from the liquid, or else the liquid would turn into vapor quickly. When the molecules collide, they transfer energy to each other in varying degrees, based on how they collide. Sometimes the transfer is so one-sided that one of the molecules ends up with enough energy to be considered past the boiling point of the liquid. If this happens near the surface of the liquid it may actually fly off into the gas and thus "evaporate".

Liquids that do not appear to evaporate visibly at a given temperature in a given gas (e.g. cooking oil at room temperature) have molecules that do not tend to transfer energy to each other in a pattern sufficient to frequently give a molecule the "escape velocity" - the heat energy - necessary to turn into vapor. However, these liquids are evaporating, it's just that the process is much slower and thus significantly less visible.

Evaporation is an essential part of the water cycle. Solar energy drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water. In hydrology, evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration.

Condensation is the change in matter of a substance to a denser phase, such as a gas (or vapor) to a liquid.[1] Condensation commonly occurs when a vapor is cooled to a liquid, but can also occur if a vapor is compressed (i.e., pressure on it increased) into a liquid, or undergoes a combination of cooling and compression. Liquid which has been condensed from a vapor is called condensate. A device or unit used to condense vapors into liquid is called a condenser. Condensers are used in heat exchangers which have various designs, and come in many sizes ranging from rather small (hand-held) to very large.

The water seen on the outside of a cold glass on a hot day is an example of condensation.
