Even though a brick weighs less in a metal hull ship a brick in the bathtub sinks but a metal hull ship in the ocean floats why?

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.


Would a bathtub weigh about 15 gallons or 15 pints?

Neither, a bathtub weighs much more.


Which object weighs more a can that floats or a can that sinks?

It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.


Even though a bowling ball weighs less than a metal-hull ship a bowling ball in a bathtub sinks but a metal-hull ship in the ocean floats why?

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...


Why does water floats on water?

Because the density of the cotton is less than that of the water. It weighs less.


Does an object less than 1.0 density sink?

No, it weighs less than water so it floats.


Why does a swimming float float?

Because it has air in it. Air weighs less than water therefore air floats.


Why do balloons float when you put helium in them?

The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)


Why does an innertube float?

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.


Why dry ice CO2 floats?

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.


Examples of solids that will float on water?

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.


How the airplane float?

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.
