By definition, an empty bottle has nothing inside.
An empty bottle has the potential to be reused or recycled. It also has air inside it, since the contents have been consumed or removed.
When you put an empty plastic bottle in the freezer, the air inside the bottle will cool and contract, causing the bottle to collapse or deform. This is due to the decrease in air pressure inside the bottle as it cools down.
Actually, an empty sealed bottle should expand slightly as altitude increases. At the altitude where the bottle is sealed, the air pressure outside the bottle is equal to the air pressure inside the bottle. When the bottle is transported to a higher altitude, the air pressure inside the bottle is greater than the air pressure outside the bottle (In other words: There are more air molecules per unit volume inside the bottle than outside). The increased air pressure inside the bottle relative to the outside pressure causes the bottle to expand slightly. An empty bottle would not collapse as altitude increases.
It is easier to squeeze an empty bottle because there is less resistance from the air inside the bottle compared to the water. The water in a full bottle creates more pressure and resistance when you try to squeeze it.
Where is the bottle? There are droplets so it is not empty. An empty bottle is empty of liquid conent but it will have air in it.

When you dip an empty bottle into water, air trapped inside the bottle escapes as bubbles due to the change in pressure and displacement of water. The air inside the bottle seeks to balance with the external pressure of the water, causing it to escape in the form of bubbles.
Actually it does empty its content until the level of the liquid inside and outside is the same.
Blowing into an empty bottle creates sound because the column of air inside the bottle vibrates at a specific frequency. This vibration produces a sound wave that resonates within the bottle, creating the audible sound you hear.
An empty bottle is typically lightweight, has no liquid inside, and makes a hollow sound when tapped. It may also have a lingering odor of whatever liquid was previously stored in it.
When an empty water bottle is placed in a freezer, the air inside the bottle cools down and contracts, creating a lower pressure in the bottle compared to the external pressure. This pressure difference causes the bottle to collapse as the external pressure compresses the bottle inward.
Putting an empty water bottle in the refrigerator will not have any significant impact on the bottle itself. However, if the bottle is left there for an extended period, it may become moist due to condensation forming on the inside.
