What are the molecular forces keeping a balloon inflated?
What keep balloon inflated is not the molecular forces but the kinetics energy of the gas molecules made the molecules to bump and create the pressure inside the balloon.
What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature?
assuming the balloon is closed, the air pressure would double
What are the two forces that affect a hot air balloon?
The downward force of gravity, and the upward buoyant force resulting from the low density air inside the balloon.
When a balloon pops what changes take place to the gas inside?
the attractive forces between gas molocules increase <======8
Does gravity go inside of a balloon?
No. Air or helium goes inside the balloon.
Can you explain why inflated balloon shoots off when its air is released?
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.

What makes a balloon go forward when the air is released?

How do balloons pop?
When you blow up a balloon, you're putting stress on the rubber. When you puncture the balloon, there's only a small space where the air can escape. The air wants to get out fast, so it forces a tear in the balloon, causing a "pop" noise.
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.
When you heat the air inside a hot air balloon, it rises. Why does this occur?
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
