WebOct 27, 2024 · In general, we know that when a sample of gas is introduced to one part of a closed container, its molecules very quickly disperse throughout the container; this process by which molecules disperse in space in response to differences in concentration is called diffusion (shown in Figure 9.4.1 ). Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. When the molecules of the liquid collide, they transfer energy to each other based on how they collide. When a …

In the gas phase the molecular forces are very weak. A gas fills its container, taking both the shape and the volume of the container. Fluids (Liquids and Gases) Liquids and gases are called fluids because they can be made to flow, or move. In any fluid, the molecules themselves are in constant, random motion, colliding with each other and ... meeting important points

WebFeb 8, 2024 · In other words, its molecules escape the body of the liquid and move freely away, as a gas. An example is when water in a pan evaporates until there is no liquid left in the pan. The reason this happens is because some molecules have high enough energy to escape the surface tension of the liquid. Evaporation results in the liquid becoming cooler.
