It can occur on a small scale, such as water vapour in the air condensing into water droplets on the surface of a cold window. But when condensation occurs on a large scale, it leads to precipitation or rain. On this scale, it is part of the global water cycle ... body armor explainedWeb24 mei 2024 · The constant temperature at which a liquid changes to vapour under normal atmospheric pressure is called the boiling point of the liquid. Boiling points of some important liquids are water (100 °C), Ethyl alcohol (78.3 °C), benzene (80.2 °C), chloroform (62 °C), sulphuric acid (280 °C), diethyl ether (35 °C), etc. cloncurry greg campbell

"WebMost surface condensers in refrigerated systems are the shell and tube type (see Figure 2.3) (McCabe and Smith, 1976). Shell and tube condensers circulate the coolant through tubes. The VOCs condense on the outside of the tubes (i.e., within the shell). Plate and frame type heat exchangers are also used as condensers in refrigerated systems. " - Involves condensing the vapour

Web22 nov. 2024 · Latent heat from condensation causes an increase in air temperature surrounding the water droplets. The warmer air rises, causing the water vapor to condense when it meets cooler air at a higher altitude. As more water vapor condenses, cloud volume increases, and the chance of precipitation increases.

WebA, B and C only. Solution: (1) A and B only. Explanation: Process A involves evaporation in which water gains heat and changes from the liquid state to the gaseous state. At B, gaseous water vapour loses heat to the cooler surroundings and condenses to form tiny water droplets (liquid) which gather to form clouds. Question 2: Web14 jul. 2024 · Condensation is the process of change of the phase of water where the vapour transforms to the liquid state. Condensation can be achieved in one of the following two ways : The cooling of air until its dew point. Saturation with water vapour until the point that it cannot hold any further quantity of water. Condensation is considered to be the ...

Web3 apr. 2024 · A condenser is a heat exchanger where refrigerant rejects heat to the atmosphere and gets condensed to a saturated liquid. Ideally, the condenser converts all the refrigerant vapor into saturated liquid by rejecting the latent heat to the atmosphere due to temperature differences.
