Can you fill helium balloons with normal air?
No it doesn't have helium. A hot air balloon derives it's lift from heated air, which is less dense and therefore lighter than normal air. A helium balloon derives it's lift from helium, a gas which at normal temperatures is less dense than normal air. So both fly 'lighter than air' but for different reasons.
Do balloons have the same charge?
no
Which will exert more pressure river water or same amount of sea water?
Salt water is denser, and therefore will exert more pressure (for two columns of the same height).
Why do balloons pop in sunlight and not in a shadow?
This is the best answer I can think of... In the sunlight, balloons receive energy from the infa-red radiation from the sun. pV=nRT... ie. for a balloon at roughly the same pressure, volume is proportional to temperature. This means that if temperature increases, volume of the balloon increases and so it pops.
When you rub two balloons with wool and gets static do they attract?
If you rub two identical balloons with the same thing, then they both have the same sign of charge, and like charges repel.
Can same type of balloons withstand the same amount of pressure?
Yes, no matter how much air is filled inside of the balloons.
What evidence supports avogadros hypothesis?
PV/NrT, pressure(volume)/amount(constant)(temperature). When your temperature, volume, and pressure are all the same, you get the same number of particles. This is avogadros hypothesis. Let's say that you have to balloons. They have the same temperature, volume, and pressure. If you weigh the gases in the balloon, you will find that there is the same amount of particles. In fact Dalton did this was able to find out the amount of particles (atoms) by the mass of objects.
What is special about the angler fishes body that it can withstand so much pressure?
There is a lot of pressure on the outside of the body, but the same amount of pressure inside the body. Angler Fish have also eveolved with very tough organs. Answer By Awesomeluke53
Why do balloons deflate in cold weather?
Because the pressure of a gas is dependent on the temperature. The same amount of gas - as what you have inside your balloon - will have a higher pressure when it's warm, and a lower pressure when it's cold. And higher pressure = more inflation. Lower pressure = less inflation.
Does a little balloon fly as far as a big balloon?
Regardless of size, both balloons will burst when atmospheric pressure becomes too much for them. Assuming the helium to rubber/latex ratio is kept the same, both balloons will burst at the same pressure. Depending on where you are in the world and the weather, the atmospheric pressure at one height differs, so it couldn't be said that both balloons will float upwards to the same height, but it can be said that they will fly to the same pressure. Thus the question "Does a little balloon fly as far as a big balloon?" is invalid, but hopefully this answer will suit your wonders.

Why is a diver able to endure the pressure at 102 feet under water?
Because your body is mostly made up of water, which is able to withstand great amounts of pressure. The parts that can't withstand the pressure very well are the air spaces, your sinuses, your lungs and your intestines if they have air trapped in them. The reason they are able to withstand the pressure is because the scuba regulator delivers air at the same pressure as the outside water, meaning that they are essentially blown back up again as they try to shrink.
Will latex balloon attract the same amount of hair as foil balloons?
im going to say yes because its made of rubber
Do balloons have the same charge?
no
Are helium balloons more dense than air baloons?
No. At the same pressure, a helium filled balloon will be less dense than an air-filled balloon.
Why cant the AV and SL valves of heart be open at same time?
it would disturb pressure gradients as it would mean same amount of pressure
What would happen if you put two positively charged balloons together?
You then have two balloons in very nearly the same place.
