EVERYDAY SCIENCE

Detailed explanation-1: -As a liquid is heated, the average kinetic energy of its particles increases. The rate of evaporation increases as more and more molecules are able to escape the liquid’s surface into the vapor phase. Eventually a point is reached when the molecules all throughout the liquid have enough kinetic energy to vaporize.

Detailed explanation-2: -Evaporation is the process by which a liquid turns into a gas. It is also one of the three main steps in the global water cycle.

Detailed explanation-3: -Vaporization is the process of converting a liquid into a gas. It is also called evaporation. Since we know that the particles of a gas are moving faster than those of a liquid, an input of energy must be required for a liquid to become a gas. The most common way to add energy to a liquid system is by adding heat.

Detailed explanation-4: -Water easily evaporates at its boiling point (212° F, 100° C) but evaporates much more slowly at its freezing point because of the heat energy required to evaporate the water. The opposite of evaporation is condensation. Condensation is the process of water vapor turning back into liquid water.

Detailed explanation-5: -Whenever a liquid turns into a gas, the particles absorb heat energy and begin to vibrate faster, increasing the separation between them. Intermolecular interactions weaken as a result of continual vibration, and molecules begin to move apart and transform into gas.
