What physical properties allow hot air balloons to fly?
Heat, the heat from the flames below the balloon cause the balloon to rise.
Does a silk cloth rubbed on a balloon cause positive or negative charge?
Negative. Rubbing fabric onto a balloon causes an electron buildup on the balloon surface because its material has high insulative properties.
How have you used the properties of gas in regards to an hot air balloon?
It is lighter than air
What is the suns properties?

Is helium in a balloon an example of matter?
Matter is anything that has volume and occupies space. Helium (in balloon) is a gas and has both these properties. So. it is an example of matter.
What two properties of a balloon makes it a good material to put over the top of the bottle?
flexible and stretchy
What hapens when a hot air balloon inflates?
It all depends on the rate the balloon loses heat, which in turn depends on the size of the balloon, the weight of the balloon, the insulation and porosity properties of the balloon fabric, and the amount of solar heating, if any, that it receives. THough, when the air heats the molecules are literally expanding and thus filling the vacancy of the balloon! This is due to the effect of physical conditions that molecules undergo.
What happens when you prick a balloon at the end opposite the opening?
You may hear a bang and the balloon shreds itself. Alternatively, depending upon the properties of the rubber, the balloon may become airborne with the knot leading the way. But if you place a piece of cellulose tape on the balloon, you may puncture it through that without the bang!
How long can a balloon stay in the air when it is inflated with hot air?
I presume you mean without an airborne heater. The answer is, there is no fixed time! It could range from a few minutes to the best part of a day. It all depends on the rate the balloon loses heat, which in turn depends on the size of the balloon, the weight of the balloon, the insulation and porosity properties of the balloon fabric, and the amount of solar heating, if any, that it receives.
