Answer: The answer is 'The air occupies space'. The bottle was not empty at all. In fact, it was filled completely with air even when you turned it upside down. That is why you notice that water does not enter the bottle when it is in an inverted position, as there was no space for air to escape.
Hope this will help you friend!!!
