Does a balloon without air weigh the same filled with air?
yes
How does the size of a balloon effect the mass it can weigh?
it's because of the ratio of the weight of the air in the balloon to the air outside the balloon
How can you weigh air in a balloon?
Identify the weight of balloon with air. And identify the mass of the balloon. Now subtract the second from the first. You get the mass of the air present in it.
When you let the air out of a balloon why do you think you feel the wind?
the breath that comes from your mouth goes into the balloon which makes that same breath. The air that you put in the balloon is the same air that will come back in your face.
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.
Does a balloon without air weigh the same filled with air?
yes
Is a flat balloon lighter than a air balloon?
depends on mass and if you include the air. same mass and not including the air they both weigh the same, air just expands the balloon and lowers the effect of gravity.

Does the air has a weight?
You can blow up a balloon and then weigh the balloon and minus it from the original weight of the balloonAnswer:Weighing air is problem because of the buoyant forces at work. If you have flattened paper bag and weigh it then open it up (effectively filling it with air), and weigh it again you find the weight is the same. In the case of a balloon, a filled balloon will weigh more than an empty balloon as it is filled with compressed air due to the tension of the balloon skin. You have no idea of the volume of room pressure air is in it.To determine this you could inflate the balloon with known volume of air using bicycle pump. Simple math would identify the volume transferred with each stroke. By knowing the weight before filling, the weight after filling, and the volume transferred it would be possible to calclate the weight per meter (or cubic foot) of room pressure air.
When a balloon is filled with air is heated does the density of the air in the balloon stay the same?
No it decreases
Is an air inside a balloon a pure substance?
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
How can we demonstrate the law of conservation of mass?
Fill a balloon with air and weigh it, freeze the balloon in liquid nitrogen and weigh it. They will weigh the same even though the state of the air has changed, mass has been preserved.
When you let the air out of a balloon why do you think you feel the wind?
the breath that comes from your mouth goes into the balloon which makes that same breath. The air that you put in the balloon is the same air that will come back in your face.
How hot is the heat inside a hot air balloon?
it is the same temperture as it is outside the air balloon:)
Which gas is used to fill a hot air balloon?
A typical hot air balloon is filled with the same air we breath.
If you trap air in a balloon and put it into warm air will it float?
If the air in the balloon is cooler than the air around it, it will sink. Hot air balloons go up because they weigh less than the air around them.
