Question

1. Did the cloud appear when you squeezed the bottle, creating high pressure on the air in the bottle, or when you released it, creating low pressure?

Answer 1

Since there is high pressure in the bottle, when you open it the speed the air escaped created a cloud.

Answer 2

The cloud appears when you release the pressure on the air in the bottle, creating low pressure.

Step-by-step explanation:

The formation of a cloud in a bottle occurs when you release the pressure on the air inside the bottle. It happens during the sudden expansion of the air, which results in adiabatic cooling. When you squeeze the bottle, you increase the pressure, and the air inside the bottle becomes warmer. However, when you release the pressure, the air cools rapidly, and if the conditions are right, you may see a cloud form as the air reaches its dew point and water vapor condenses into tiny water droplets. This phenomenon is often used to demonstrate the principles of adiabatic cooling and cloud formation.
