Evaporation is the correct answer for the process demonstrated in the experiment.
Explanation:
Evaporation is the process by which a liquid changes into a gas or vapor. In this experiment, Sunil took water and dissolved salt in it. When the salty water was placed under sunlight for four days, only the crystals of salt were found, and the water seemed to have disappeared. This is because the process of evaporation occurred.
Here is a detailed explanation of why the process demonstrated in the experiment is evaporation:
1. Dissolving salt in water:
- Sunil took some water and added salt to it, stirring until the salt dissolved completely. This created a solution of salty water.
2. Sunlight and heat:
- Sunlight provides energy in the form of heat. When the salty water was placed under sunlight for four days, the heat from the sun caused the water to evaporate.
3. Evaporation:
- During evaporation, the heat energy provided by the sun causes the water molecules in the salty water to gain enough energy to break free from the liquid and escape into the air as water vapor.
- The water vapor molecules are lighter than the salt molecules, so they rise up into the atmosphere.
4. Salt crystals:
- As the water evaporates, the salt molecules that were dissolved in the water remain behind, forming salt crystals.
- The salt crystals are left behind because they are not volatile like water and do not evaporate.
In conclusion, the process demonstrated in the experiment is evaporation. The heat from the sunlight caused the water molecules in the salty water to gain energy and escape into the air as water vapor, leaving behind the salt crystals. This process is a natural occurrence that happens when a liquid is exposed to heat and results in the conversion of the liquid into a gas or vapor.
