Which step in the water cycle loses energy?
When liquid water loses thermal energy, it undergoes freezing : changing state from a liquid to a solid. We see many examples of this in everyday life. Puddles, ponds, lakes, and even parts of oceans freeze when the water becomes cold enough.
When water condenses does it lose or gain energy?
The energy lost is transferred to the cold surface. Thus, condensation occurs due to a loss of energy from the vapour. It’s important to note that the conservation of energy still holds,so the energy lost of gained by the liquid / vapour is inversely gained or lost from the surface in contact with it.
Does boiling need energy?
When liquids boil the particles must have sufficient energy to break away from the liquid and to diffuse through the surrounding air particles.
What happens to the water when it condenses?
Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
Which is an example of the water cycle?
When water vapor loses thermal energy and becomes liquid water, condensation has occurred. Rain and dew are examples of condensation. A cold can of pop placed outside on a hot summer day often accumulates water droplets. This is because water vapor in the air condenses when the cold can cools it.
How are water droplets formed in the water cycle?
The puddle of water on the table gains heat from the warmer surrounding air to evaporate to form water vapour. The warmer water vapour from the surrounding air came into contact with the cooler outer surface of the glass cup, lost heat to it and condensed to form water droplets.
How does the sun’s heat affect the water cycle?
Heat from the Sun can melt ice, producing liquid water. The Sun’s heat also causes liquid water to evaporate. Evaporation creates water vapor, a gas that rises into the air. But just as heat from the Sun changes water, so does the absence of heat.
How is the movement of water related to the hydrologic cycle?
Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years. Earth’s water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth.
