This is strait from the apex questions. ITS DEW POINT - C.
The dew point is the varying temperature at which atmospheric humidity condenses. If the air temperature drops below the dew point, dew and condensation form.
The air cooling of a chiller signifies , the cooling of radiator. in a chiller the compressor compressors the gas which on expansion cools in side Copper tubes causing the chilling effect. The refrigerants get heated up when compressed in a compressor. this heated refrigerant is cooled by blowing air in air cooled chillers. There are also water cooled chillers.
either by air or water.
answ2, Essentially all the components of air may be frozen into a solid at low temperatures. Oxygen, Nitrogen, Carbon dioxide, Argon, Neon all have freezing points. Helium (only a trace gas in the air) does not freeze.A1. Air does not have a melting point. It cannot melt or freeze. But that all depends on the chemical composition. For example, if the air your talking about is just water vapor, then it can evaporate and condense. But air itself cannot freeze or melt, therefore it does not have a melting point.
The water will condense forming dew.
The air needs to be cooled, the amount depending on how much water vapour is in it. When it's cooled sufficiently the water vapour will condense on solid things as water, or become very small droplets (fog/cloud). When this happens in the early mornings we call it dew, and the temperature at which the water will condense is known as the dewpoint.
The dew point is the temperature at which water will condense out of the air. If the dew point were above the temperature, that would mean that some of the water vapor in the air should have already condensed out. In such a situation, the excess water WOULD condense out, lowering the amount of water vapor and consequently the dew point.
As air molecules are cooled, they condense and form a liquid, and if cooled even further, will form a solid.
There must be moisture in the air. When cooled, the water vapor in the air becomes liquid water- but if there is no moisture, then it cannot condense.
Water will start to condense onto objects when the air becomes "saturated" - when the temperature drops to the dew point (at which point the relative humidity will be 100%).
when the temperature reaches the dew point.
when the temperature reaches the dew point.
It evaporates, because when it is low there is not enough CO2 to condense the air.
At temperatures below the dew point there is less evaporation than condensation. Drops and droplets condense and grow. At temperatures above the dew point there is more evaporation than condensation, drops and droplets evaporate.
Air condenser can be used when the boiling point of the solvent is very high, as the air temperature will to sufficient to condense the solvent vapour. Water condenser is generally used when the solvent boiling temperature is less e.g., water, ethanol etc.
Its both air and water cooled.
