Condensation is the process by which a gas or vapor changes into a liquid. This occurs when the temperature of the gas or vapor drops below its dew point, the temperature at which the air becomes saturated with water vapor and cannot hold any more. When this happens, the excess water vapor condenses into liquid water droplets, forming clouds, fog, or dew.
Factors Affecting Condensation
Several factors can affect the condensation process:
Temperature: Lowering the temperature of the gas or vapor increases the likelihood of condensation.
Humidity: Higher humidity levels lead to a greater likelihood of condensation, as the air is closer to being saturated with water vapor.
Surface Area: Increasing the surface area for condensation to occur, such as with the presence of dust particles or aerosols, can promote condensation.
Examples of Condensation
Condensation is a common occurrence in everyday life. Some examples include:
Number and Operations: In grade 4, students used equivalent fractions to determine the decimal representations of fractions that they could represent with terminating decimals. Students now use division to express any fraction as a decimal, including fractions that they must represent with infinite decimals. They find this method useful when working with proportions, especially those involving percents. Students connect their work with dividing fractions to solving equations of the form ax = b, where a and b are fractions. Students continue to develop their understanding of multiplication and division and the structure of numbers by determining if a counting number greater than 1 is a prime, and if it is not, by factoring it into a product of primes.
