Water exists in three states: solid (ice), liquid (water), and gas (water vapor). We encounter ice in freezers, drink liquid water, and see steam rising when water boils, showcasing its versatility in everyday life.

The best description of condensation is (iv): the conversion of water vapor into its liquid state. This process occurs when water vapor cools and forms droplets, contributing to cloud formation and precipitation.
Acting out the water cycle involves students role-playing stages like evaporation, condensation, precipitation, and collection. This interactive activity helps illustrate how water moves through its cycle, making the concept engaging and memorable.
Leaving sludge in heaps allows excess water to drain out, reducing its weight and volume. This makes transportation cheaper and easier, while letting it partially decompose improves safety and reduces handling risks.
To speed up drying clothes on a rainy day, use a fan or dehumidifier to increase air circulation and reduce humidity. Alternatively, use a heater to warm the air, which enhances evaporation.
Deposition is the process where water vapor changes directly into solid ice without becoming liquid first. This occurs when water vapor loses energy and forms ice crystals, such as frost on cold surfaces.
Sublimation is the process where ice (solid water) directly transitions into water vapor (gas) without first becoming liquid. This occurs when ice absorbs enough energy to bypass the liquid phase.
Water changes from solid (ice) to liquid (water) through the process of melting. When heat is applied, the temperature rises, causing the ice to absorb energy and transition into a liquid state.
Water exists in three states: solid (ice), liquid (water), and gas (steam or water vapor). Each state has distinct properties and transitions between states occur due to changes in temperature and pressure.
Natural grass feels cooler than plastic grass because it undergoes evaporation, which absorbs heat and cools the air. Plastic grass, however, does not evaporate and absorbs and retains more heat, making the surrounding area warmer.
