This physical property is called condensation. An example of condensation in nature is the formation of clouds. C. Several hours later‚ the ice cubes are no longer present. Give another example of this physical property of matter. This physical property is called phase change. Another example of phase

is driven by the energy from the sun. When water vapor cools as it undergoes the process of condensation. Condensation is the process of water going from the gas phase into the liquid phase. In order for water to condensate‚ the moisture must have some form of particulate to attach to. This particulate can be in the form of dust‚ smoke‚ or other forms of pollution as well as solid surfaces. When condensation occurs in the atmosphere and falls back to Earth we again have precipitation. This is why it

Typical applications involve heating or cooling of a fluid stream of concern and evaporation or condensation of single- or multicomponent fluid streams. In a few heat exchangers‚ the fluids exchanging heat are in direct contact. In most heat exchangers‚ heat transfer between fluids takes place through a separating wall or into and out of a wall in a transient

macromolecules made from a few hundred to a few thousand monosaccharides. Formation of glycogen and cellulose by condensation reactions to form glycosidic bonds: These are formed when two monosaccharides are condensed together. One monosaccharide loses an H atom from carbon atom number 1 and the other loses an OH group from carbon 4 to form the bond. The reaction‚ which is called a condensation reaction‚ involves the loss of water (H2O) and the formation of an 1‚4-glycosidic bond. Depending on the monosaccharides

Synthesis of Aspirin and Oil of Wintergreen Janelle Alyssa P. Prudente De La Salle University-Dasmariñas Dasmariñas City‚ Cavite‚ Philippines ABSTRACT In this experiment‚ acetylsalicylic acid commonly known as aspirin and methyl salicylate‚ commonly known as oil of wintergreen‚ was synthesized from salicylic acid. This study will show that it is possible to show two very different organic compounds from the same common starting material. For the synthesis of aspirin‚ salicylic acid
