Density.
A 5-foot steel bathtub typically weighs around 100-150 pounds, but this can vary depending on the specific design and thickness of the steel used.
An example of a solid that floats on water is a needle, even though its density is greater than that of a water it still floats, this is because of Intermolecular Forces.Anything lighter (less dense) than water will float; this includes wood, some clothing, metal objects (like boats), provided they have enough air in between, etc.

Because any amount of wood weighs less than the same amount of water does.Which is just an easier way of saying that the density of almost all varieties of woodis less than the density of water.

It floats because the shape of the hull with a large cavity inside displacing the water counteracts the weight of the metal hull. The water displacement counteracts the force of gravity, spreading the weight of the boat out across a larger surface area with a great tensile strength, resisting the force of gravity.
Neither, a bathtub weighs much more.
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
The water that the hull in ship displaces is way more heavier than the hull itself, so the water surface holds the ship floating... If you had a bowling ball made of hull-material it would sink anyway.. What it does that the ship floats is the amount of displaced water, which in weight is going to be higher than the floating object's weight itself...
Because the density of the cotton is less than that of the water. It weighs less.
No, it weighs less than water so it floats.
Because it has air in it. Air weighs less than water therefore air floats.
An innertube floats for the same reason that a balloon filled with helium floats in the air. In a helium balloon the gas is lighter than the air. Air in an innertube weighs less than the water and therefore floats to the top. This is called buoyancy. It weighs less than the water but more than the air above the water due to the rubber of the tube. This is why it stays on the surface and does not float away into the sky.

CO2 floats because its density is less then water. Anything will float if its density is less then water. That is; when a certain volume of CO2 (or anything else) weighs less then the same volume of water.
The same way anything floats, by displacing an amount of water that weighs as much as it does. Airplanes that are meant to float on water typically either have boat-like hulls or floats whose purpose is to displace enough water to allow the airplane to float.
Even though Ice is H2O, and so is water (the same substance), they are different states of matter, the Ice is a solid, and the water is a liquid. Because the particles are more compact, so the same amount of volume weighs more, so the Ice travels down through the water.
