This is osmosis. Vinegar isn't pure acetic acid...it's a 5% solution in water. The concentration of water is higher in the vinegar than it is in the egg...so via osmosis, the water moves from the area of high concentration (outside the egg) to the area of low concentration (inside the egg) causing it to grow. Of course it helps that the acid (vinegar - acetic acid) will dissolve the egg shell (calcium carbonate) as well.

<u>Answer</u>:
1. Rain droplets on the window - precipitation
2. Fog on the bathroom mirror after a hot shower - condensation
3. Drying of a wet modded floor - evaporation
<u>Explanation</u> :
The <em>water cycle</em> describes the cyclic movement of water between the land and the atmosphere.
The water cycle involves many processes such as evaporation, condensation, and precipitation.
1. <u>Evaporation</u>
- The process of evaporation involves the heating up of water present in various sources and its conversion into gas form.
- Since drying of wet modded floor involves the conversion of water into gas due to heat, this process is an example of <em>evaporation</em>.
2. <u>Condensation</u>
- The process of condensation involves the cooling of the evaporated water as it reaches the atmosphere resulting in the formation of clouds.
- Similarly, after a hot shower, the water cools down on the mirror and forms fog. Thus, this is an example of <em>condensation</em>.
3. <u>Precipitation</u>
- When too much water has been collected in the clouds they become too heavy to hold water, and thus, the water falls down on the surface of the earth in the form of rain, snow or sleet. This process is known as precipitation.
- Thus, rain droplets seen on the window is an example of <em>precipitation</em>.
