A bottle contains 300 cm cube(3) of air. The volume of air in the strynge is 45cm cube(3).  Please help me what is the answer

A bottle contains 300 cm cube(3) of air. The volume of air in the strynge is 45cm cube(3). When the plunger of the strynge is oushed completely, the volume of air in the strynge becomes 0cm cube(3). , and the volume of air in a bottle is?

A. increases to 345 cm cube(3)

B. decreases to 255cm cube(3)

C. stays the same

Once you compress all the air in the strynge will go in to the bottle. As a result of that the numbers of air particles in the bottle will increase. Here volume of air means the volume of the bottle. Air particles are distributed inside the bottle. So if you have less air particles they will remain inside the bottle at longer distance among particles. When you add more particles they will come closer. So volume is constant. But pressure will increase. When you add more and more air at some instance the pressure increment will become too high and the bottle will blow off.

So the answer is that the volume remain same.
