EVERYDAY SCIENCE

Detailed explanation-1: -Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle.

Detailed explanation-2: -When water is heated it evaporates, which means it turns into water vapor and expands. At 100℃ it boils, thus rapidly evaporating. And at boiling point, the invisible gas of steam is created. The opposite of evaporation is condensation, which is when water vapor condenses back into tiny droplets of water.

Detailed explanation-3: -Evaporation is a key step in the water cycle. Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing-it is evaporating into a gas, called water vapor.

Detailed explanation-4: -Conversion of water into steam is a physical change.

Detailed explanation-5: -(i) “Evaporation is the process of transformation of “liquid state to gaseous state” by heating below its boiling point. We can observe this in our everyday life also such as: Hot tea getting cold. Wet clothes drying in the sun.
