no
no it will not. because a balloon filled with hydrogen floats only because it is lighter than air so when there is a vacuum it will not float. it is like oil and water if there is no water oil is on the bottom if there is water it is on the top.
A small piece of feces is mixed with the fecal float solution in a special container. Then the container is filled with solution until it a meniscus forms at the top. Set a coverslip on that and then wait 10 - 15 minutes.
Cullets doesn't float on water.
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)
Helium
No, the baby never filled them with air from their first breath, therefore they are fluid filled...and won't float.
You can use a milk container filled with water to weight it down so it doesn't float. You can put one or two bricks in the tank.
markers float because they are less weight. and it doesnt have metle on it.
It depends if the carton is full or not. If the carton is empty, then it will float. If their is milk in the container, then it won't float.
Whether or not you float has nothing to do with vacuum. You float because you are too far away from the earth (or other massive objects) for their gravity to have any noticeable effect on you. It just so happens that this occurs in space where natural vacuum may be found.
it would sink(DrStrong) The answer above may be correct, or the object might float. It depends on the density of the container. If the container is a foam cooler filled with water, it's going to be floating. That's because the weight of matter contained within the outer surface of the foam cooler will be slightly less than the weight of water of the same volume. You can call that a gross density if you wish. However, if the container was made of iron, then there is no way it will float if it is completely filled with water, since the gross density will be greater than that of water.See Archimedes Principle.
You can determine if a rock can float by comparing its density to the density of water. If the rock is denser than water, it will sink. If the rock is less dense than water, it will float. This can be tested by placing the rock in a container filled with water and observing its behavior.
