Answer: Option (d) is the correct answer.
Explanation:
In water cycle, water from clouds fall in the form of rain, snow etc. This water travels through the surface of mountains and passes through rivers, oceans etc and gets evaporated due to heat from Sun.
When water evaporates then it absorbs energy in the form of heat from Sun and when water condenses then heat is released.
Therefore, water gains energy during evaporation and releases it during condensation.
Because the bond order in an oxygen gas is shown to be equal to 2, the idea furthermore supports the prediction of the molecular orbital theory in the paramagnetism of oxygen gas. This theory is primarily used when electrons are not included in the individual bonds for determining molecular structure.
The two parts of a solution are a Solute and the other one is a Solvent. The Solute is the substance that dissolves, and the Solvent is the majority of the solution.
