6.what change of state is occurring during condensation?
1 If air were free of tiny particles, called aerosols, condensation would only occur when the air was extremely supersaturated with water vapour. In the atmosphere, however, there is an abundant supply of aerosols, which serve as nuclei, called condensation nuclei, on which water vapour may condense. Dewdrops are often found on a spider’s web early in the morning after a cold night. Water that is present as a gas in the air cools down and changes into tiny drops of liquid water on leaves and windows. This change from gas to liquid is called condensation. find out more Condensation, deposition of a liquid or a solid from its vapour, generally upon a surface that is cooler than the adjacent gas. A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of the liquid or solid phase of the substance at the temperature of the surface where condensation occurs. Heat is released when a vapour condenses. Even without boiling water in a kettle, some of the liquid water changes to gas. This is evaporation. It occurs when a liquid turns into a gas far below its boiling point. There are always some particles in a liquid that have enough energy to break free from the rest to become a gas. In the atmosphere the relative humidity of the air is increased, and condensation results when air temperature is reduced to the dew point or when sufficient water vapour is added to saturate the air. Condensation accounts for the formation of dew, fog, and clouds. For rain to occur, other physical processes are required. Condensation is a process by which a substance changes from a gaseous state to a liquid state. As a gas cools, it loses heat, or thermal energy. The particles that make up the gas move more slowly; that allows the attractive forces among them to increase, causing droplets of liquid to form. A substance that is a gas can change to a liquid, and a liquid substance can change to a gas. solar plasma The glowing corona of the Sun visible during a total eclipse is made of a fourth state of matter called plasma. All matter exists as solids, liquids, or gases. These are called the states of matter. Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid). This change is called MELTING. If water is heated, it changes to steam (a gas). This change is called BOILING. When solid, the particles of a substance are tightly packed together, making it rigid. A substance can change from a solid state to a liquid state, and from a liquid state to a solid state. climate and weather. 1  atmosphere and cloud processes (in atmosphere: Condensation) 2  dew-point temperature (in climate (meteorology): Relation between temperature and humidity) 3  ocean temperatures (in seawater: Thermal properties) 4  precipitation (in hydrologic sciences: Precipitation)
