Question

HOW DOES EVAPORATION DIFFER FROM COOLING

Answer 1

Answer:

Liquid evaporating from a surface has a cooling effect. And different liquids have this effect to different degrees. For example, rubbing alcohol has more of an evaporative cooling effect than water. Alcohol evaporates comparatively more quickly than water, so scientists class it as a "volatile" liquid. But regardless of the liquid, they all follow the same principle of evaporative cooling. In its liquid state, the substance—whether water or alcohol—has a certain heat content, which is central to the process. Also critical to this are two of the three basic phases of matter: liquid and vapor.

Answer 2

Evaporation differs from cooling when the liquid state, that is, the water turns into a gaseous state (steam), and evaporation continues to the extent.

Explanation:

Evaporation is the process of converting the liquid state of an aggregate into a gas. It process requires few amounts of thermal energy.

• During evaporation, the liquid particles on the surface become hot and begin to oscillate with greater amplitude.
• The particles that are present enter the gas phase when bonds are formed between them and the remaining liquid is broken down.
• This reduces the average energy of the liquid and creates a cooling effect.
• When the molecules on the surface consume enough energy to exceed the vapor pressure, the liquid particles escape and like the surrounding sky as a gas.
• The energy of the liquid vaporized during evaporation lowers the temperature of the liquid, resulting in evaporative cooling.
