Charles' law - states that gases expand when heated. When the gas expands it becomes less dense (because it now has the same mass but a larger volume). The reduction in density causes the balloon to rise
Usually, the air pressure inside a balloon is very high because the plastic outer shell of a balloon wants to contract and press the air into a small space. High in the atmosphere, air pressure is much lower than on the ground. When the air pressure outside a balloon is bigger than the air pressure inside, the balloon switches from wanting to push in on the air to the air pushing on the balloon. as this happens to some parts of a balloon and not others, it is uneven and the balloon pops.Answer:There are two distinct cases:For child's rubber balloon the air inside is at higher pressure because it is being squeezed by the rubber that wants to return to its original size. Just like you have to apply pressure to a rubber band to keep it stretched.In the case of hot air balloons the pressure on the inside of the balloon is the same as the atmospheric pressure. The balloon in this case is like an upside down bucket of air that would like to rise. It fills the container but shares the pressure of its surroundings.

How does intensity apply to color?

sometimes, depending on how full the water balloon is.
use a metal spatula, and apply dish soap to the balloon so it can wash off easier
NO. Use beeswax. Candle wax is too brittle and won't adhere well.
You should always treat both ears. If just one ear seems to be problematic you should use the same candle for both ears using the last minute of the burning candle on the second ear.
because heat expands things... and the heat expands the air in the bottle and the air in the balloon... the only place for the air to go, since it cannot expand the bottle... is out into the balloon, increasing the pressure there and inflating the balloon. :-)
If you are an employee of Macy's you can apply to participate in the parade. You may be selected to hold a balloon or be one of the walkers who accompany floats, often in costume.
the hot air is more dense then the actual air
A lighted or magnified cosmetic mirror allows the user to more accurately see what they are doing while they apply beauty products to their face. Magnification and brighter light allows one to be more precise when doing activities such as applying mascara or shaping their eyebrows.
The reason is because the material of the balloon actually has very tiny holes, like our skin, so substances will pass through them. (that's why we apply moisterisers) So the highly pressured air/ helium in the balloon will diffuse out to an area of lower concentration. =)
A loan where your payments apply only to the interest and nothing towards the principal. There is usually a "balloon" payment required at the end of these loans - that is when the principal is paid ... in full. Some people cannot pay that "balloon" when it comes due, so there are others who will purchase your balloon, and then you pay them interest only on that balloon and have yet another balloon later on. It becomes an endless cycle and very very profitable for those who purchase such balloons.
A balloon powered car is moves because the balloon pushes out air. Whenever something exerts a force on something else (in other words, the balloon is exerting force on the air), then the object being pushed always exerts an equal and opposite reaction force on the object exerting force on it (in other words, the air exerts force on the balloon). Because the balloon is attached to the car, when the balloon is pushed by the air, the car is pushed. The law that for every force there is an equal and opposite reaction force is Newton's Third Law of Motion.
