Answer: Option (A) is the correct answer.
Step-by-step explanation:
When a liquid state changes into gaseous state then this process is known as evaporation.
Since, molecules in a liquid are slightly away from each other as compared to molecules in a solid state. As molecules in a liquid state have more kinetic energy. But when heat is provided to a liquid then its molecules gain even more energy.
Thus, there occurs change in state from liquid to gas.
Hence, we can conclude that during evaporation a liquid changes to a gas.
