When the balloon is filled with water, it creates pressure on the water inside the straw, causing the water level in the straw to rise. When the balloon is squeezed, the pressure is increased, causing the water level in the straw to rise even further due to the increased force.
provided the balloon has not reached its elastic limit (it has burst!), the air pressure inside and outside will essentially be equal. [The pressure inside will be slightly less, which is where the lift comes from.] But even at altitude, the pressure will be approximately equal in and out, for at altitude, the balloon will have swelled, thus reducing the internal pressure. It will eventually reach an altitude at which the internal pressure and the external pressure will be equal, and the balloon will have reached maximum expansion. Filled at sea level, a balloon will seem empty and floppy, and very tall and thin. At altitude the balloon will fill out as the external pressure reduces.
Helium only needs two electrons to have a filled outermost energy level.
As you rise in elevation, the pressure around you decreases. This lower pressure would cause the balloon to expand, and burst if it was inflated to much originally. By starting it off only partly filled, it will expand to a normal size and not explode.
The question is not clear but i think it will be the same original size as it was initially.
The inverted drinking glass must be pushed to a depth where the water level inside the glass is halfway between the original water level and the top of the glass. This ensures that the volume of enclosed air is squeezed to half.
A balloon filled with hydrogen rises until it reaches a level in the atmosphere where the air pressure outside the balloon is equal to the pressure inside the balloon. At this point, the balloon stops rising because the difference in pressure is no longer enough to overcome the force of gravity pulling it downward.
One of the specific applications to Charles' Law is the Hot-Air Balloon, as the balloon is filled up with hot air, the rising temperature lowers the density of the balloon below atmospheric level helping the balloon to rise up into the air
Because the balloon gets stretched when it is inflated and it is trying to contract again it pushes inwards. The molecules in the air get compressed slightly because of the confined space, meaning that the density of the air in the balloon increases. The molecules move closer together = more Energy = slightly warmer.
The density of a balloon depends on the gas it is filled with. For example, a balloon filled with helium is less dense than the surrounding air, causing it to float. The density of a balloon can also be affected by additional factors like the material it is made of and any objects it contains.

By definition, anything 'filled with vacuum' would weigh nothing, as a vacuum means an area that contains no matter. Since the balloon would need matter in it to weigh anything, a vacuum balloon would be lighter than the heavier air around it, as air is made of matter.
Free the balloon at the bottom and as the red balloon goes up pop the tnt balloon as it passes it and pop the last tnt balloon.
If it's a normal balloon like the one you'd see at a birthday, it's because it's filled with helium which is lighter than the air around us (it's hard to imagine air has weight, but it does at a molecular level). If you're talking about a hot air balloon, it floats because the air in the balloon is hotter than the air around it, and heat rises (again due to molecular-level activity). Hope that helps!

The air inside the balloon is at a higher pressure than atmospheric pressure so the gas molecules inside the balloon are closer together on average than gas molecules outside the balloon. This means that the repulsive forces between the gas molecules inside the balloon are greater than the repulsive forces between the gas molecules outside it. When the balloon is opened, the gas molecules in the open end at the border between the higher pressure interior and lower pressure exterior will experience a greater repulsive force from the gas molecules inside the balloon than the molecules on the outside. This means that they experience a net force pushing them out of the balloon. As these gas molecules are pushed out by the gas inside the balloon, they push back on it with an equal and opposite force (due to Newton's 3rd Law of Motion). This equal and opposite reaction force causes the gas in the balloon to be pushed in the opposite direction to the escaping gas, which in turn pushes the balloon. As more and more gas escapes, the reaction force on the balloon continues to accelerate it, making it shoot off, until enough gas has escaped for the pressure inside the balloon to have dropped to the same level as the pressure outside the balloon.
75 atmospheres of pressure is 1125 pounds per square inch. A balloon would be unlikely to withstand this pressure.
