Consider a sealed container half-filled with water. Which statement best describes what occurs in the container? a. Water evaporates until the air is saturated with water vapor; at this point, no more water evaporates . b . Water evaporates until the air is overly saturated (super-por: at this point, no more water evaporates. Water evaporates until the air is overly saturated (supersaturated) with water, and most of this water recondenses; this cycle continues until a certain amount of water vapor is present, and then the cycle ceases. c. Water does not evaporate because the container is sealed. d. Water evaporates. and then water evaporates and recondenses simultaneously and continuously. e. Water evaporates until it is eventually all in vapor form. Explain each choice. Justify your choice, and for choices you did not pick. explain what is wrong with them.

Solution Summary: The author explains that the best statement, which describes the evaporation of water in a sealed container was given from set of statements.
Consider a sealed container half-filled with water. Which statement best describes what occurs in the container?
a. Water evaporates until the air is saturated with water vapor; at this point, no more water evaporates.
b. Water evaporates until the air is overly saturated (super-por: at this point, no more water evaporates. Water evaporates until the air is overly saturated (supersaturated) with water, and most of this water recondenses; this cycle continues until a certain amount of water vapor is present, and then the cycle ceases.
c. Water does not evaporate because the container is sealed.
d. Water evaporates. and then water evaporates and recondenses simultaneously and continuously.
e. Water evaporates until it is eventually all in vapor form.
Explain each choice. Justify your choice, and for choices you did not pick. explain what is wrong with them.
