Answer

Explanation:

Step1: Understand cloud - formation principle

Clouds form when water vapor condenses. In this experiment, the key is the change in pressure and temperature.

Step2: Analyze Part A

When the students release the bottle, the volume inside the bottle increases. According to Boyle's law ($P_1V_1 = P_2V_2$), when volume increases, pressure decreases. A decrease in pressure causes a decrease in temperature (Gay - Lussac's law $P_1/T_1=P_2/T_2$), and water vapor condenses to form a cloud. So the cloud forms when students release the bottle.

Step3: Analyze Part B

When the students release the bottle, the air pressure decreased. According to the ideal gas law and the relationship between pressure and temperature, a decrease in pressure causes a decrease in temperature. This drop in temperature causes water molecules to condense into a cloud.

Answer:

Part A: A. when students release the bottle Part B: The air pressure decreased, which caused the temperature to decrease.
