What object has a less density than water?
A full balloon
Why is a balloon heavier when it is blown up with air?
This depends on whether you consider what is inside the balloon to be a part of the balloon, since the weight of the balloon skin will remain the same regardless of what is inside it. If, however, you consider the contents of the balloon to constitute a part of the balloon's mass then it will always be heavier when inflated, regardless of the density of the substance with which it is inflated. However, in this case the density of the balloon will fall when inflated if the contents are less dense than the material of the balloon, which is highly likely since the substance would probably be a gas. Therefore the balloon would be heavier but less dense.
Why does not a balloon full of oxygen float?
oxygen is less dense than water thus it rises
What scientific principle explains hot air balloon flight?
The scientific principle that allows hot air balloons is the following.It's all in the name: hot air balloon. Hot air is blown into the opening at the bottom of the balloon. Because hot air is less dense than cold air, it rises. Since the balloon becomes filled with air that is less dense that that surrounding it, the balloon rises. If you want to make the hot air balloon rise faster, you have to either put less people in it or weigh it down less with less luggage or extra stuff.
Why does an empty cylinder weigh less than a filled one?
Because it hasn't got any extra mass inside it.
If empty barrel weighs 10 pounds what can you put in the barrel so that it weighs less?
You could put a flexible bladder (balloon) filled with helium in it. The classic answer to this old question is: Fill it full of holes.
What object has a less density than water?
A full balloon
What weighs more 50 pints or 50 pounds?
That depends on what's in the pints. If they're full of air, they weigh much less than 50 pounds. If they're full of water, they weigh pretty close to 50 pounds. If they're full of stones or gold, they weigh a lot more than 50 pounds. If the pints are empty, they weigh nothing at all.
How much does an empty box weigh?
an empty bow depending on its size can weigh between 2 oz. to 100 oz. it can though weigh less or more depending like i said on the size of the box
How do mass and inertia make it easier to pick up an empty juice bottle and a full juice bottle?
An empty bottle has less mass than a full bottle. This means that the empty bottle has less force to overcome when lifted which corresponds to less work to lift it.

Why does an empty gas cylinder weighs less than a filled one?
An empty gas container actually weighs less than a full container.
Why does putting a balloon filled with helium into an empty 10 pound barrel make it weigh less?
Helium has a lower density than air, therefore replacing the air in the barrel with helium decreases the mass of the barrel system thus the weight is decreased.
What can make your balloon powered car go faster?
use bigger wheels and use less friction on the ground make it weigh less
