Water’s Disappearing Act refers to the process of evaporation where water changes from a liquid state to vapor. It seems to disappear as it evaporates into the air, though it actually turns into water vapor.

Ice is the solid state of water with a fixed shape and volume, while water in its liquid state flows and takes the shape of its container. Both ice and water are forms of H₂O.
Yes, water in puddles disappears due to evaporation. As the sun heats the water, it turns into water vapor, which rises into the air. The process gradually reduces the amount of water in the puddle.
Yes, the reason for water disappearing from utensils is similar. The water evaporates over time as it absorbs heat from the surroundings, changing from liquid to vapor and dispersing into the air.
When water is sprinkled on a hot pan, it evaporates quickly. The heat causes the water to change from liquid to vapor, which disperses into the air, making it seem like it has disappeared.
Hand sanitizer disappears as you rub it because it evaporates. The alcohol and other components in the sanitizer change from liquid to vapor due to the heat from your hands, leaving no residue behind.
Water droplets appear on the outer surface of a glass tumbler because the cold glass cools the air around it. This cooling causes moisture in the air to condense into droplets on the glass.
Dew drops are more visible in the morning because overnight cooling causes water vapor to condense on cool surfaces like plants. As temperatures drop, the air’s capacity to hold moisture decreases, forming dew.
The mass of cold water on the digital weighing balance will remain the same. Mass is conserved unless water evaporates or external substances are added. Temperature changes alone do not affect the mass of water.
Fungi growing on the barks of trees are called corticolous. These fungi colonize the outer surface of tree bark, where they play various ecological roles, including decomposition and nutrient cycling. Corticolous fungi contribute to the diversity and health of forest ...
