About 91.5 cubic inches.
With less gas inside the bottle, it will weigh less. But not by very much, for the mass of the volume of air is slight. If he bottle is evacuated, then its shape will change slightly - but once again, a small amount. If the bottle is fragile, it may collapse. This would be expected for a plastic bottle, such as a soft drink bottle.
Water, an empty plastic bottle and an air pump.
If you are in Science Olympiad, a bottle rocket is a modified 2 liter bottle designed to stay up in the air longer than its competitors. Another type of bottle rocket is a type of firework you place in a bottle to make it launch.
air doesn't have enough mass. water is needed for it's mass. a plastic drink bottle can't hold enough air, the pressure would be to high.
it would implode.
Air
yes because air can spread out.
Ballons are made of an elastic plastic while a bottle in a harder plastic
the plastic becomes weak
yes, air will compress in any enclosed area

The idea is to divide the mass by the volume. I assume the half liter is what fits inside the bottle; in theory, the actual volume of the bottle plus the contents should be slightly more. Also, in theory you'll have to add a small amount of mass for the air inside. If the bottle is filled with air, then you'll actually get the average density of the bottle plus the air.
The air inside shrinks its space needed.
Let's say that y­ou take a plastic 1-liter soda bottle, empty out the soft drink it contains, put the cap back on it (so you have a sealed bottle full of air), tie a string around it like you would a balloon, and dive down to the bottom of the deep end of a swimming pool with it. Since the bottle is full of air, you can imagine it will have a strong desire to rise to the surface. You can sit on the bottom of the pool with it, holding the string, and it will act just like a helium balloon does in air. If you let go of the string the bottle will quickly rise to the surface of the water.The reason that this soda bottle "balloon" wants to rise in the water is because water is a fluid and the 1-liter bottle is displacing one liter of that fluid. The bottle and the air in it weigh perhaps an ounce at most (1 liter of air weighs about a gram, and the bottle is very light as well). The liter of water it displaces, however, weights about 1,000 grams (2.2 pounds or so). Because the weight of the bottle and its air is less than the weight of the water it displaces, the bottle floats. This is the law of buoyancy.Another way is the way a hot air balloon works. Put a gas fire almost in the balloon. The fire puts really hot air in the balloon. The material the balloon is made of keeps the hot air in. the balloon rises because hot rises. the temperature must be a certain amount higher then the air out side depending on the load.
It's a process called condensation caused by humid air striking a much colder surface. Generally the colder air is the less moisture it can carry. So when the air around you meets the side of the bottle it begins to cool, and can't care as much moisture as it had been. The moisture it can't carry is deposited on the side of the bottle as condensation.
