What is an example of a solid liquid and gas that might be found in a hot air balloon?
Feelunique
The solids will be the balloon and the basket, the propane burner and so on.
The liquid part will be the condensation on the inside of the balloon resulting from the burning.
The gas part is the hot air and the water vapour.
[note. the water vapour (lighter than air!) provides some of the lift!]

Which of these liquids flows fastest when poured?
The liquid that flows the fastest when poured is the least viscus. This liquid might be liquid water for example.
What might happen when you prick the balloon?
Usually the balloon will burst.
What might happen if you prick the balloon?
Generally, it will pop. But it also depends on what you prick it with. A sharpened pencil for example will undoubtedly pop it, no problems there. But an UNsharpened pencil may take a bit more work to pop a balloon, as it does not have a sharp edge.
Why do balloons rise in the air?
A balloon rises in the air only if the balloon has a lower mass than an equal volume of the air surrounding it.That might be the case if the balloon were filled with a light gas such as helium, for example. The balloon rises because the pressure of the air around it pushes it up in the same way that water causes an air bubble to rise.
Will a lit cigarette ignite a helium balloon?
Helium is not flammable. However, the cigarette might puncture the balloon.
What are bad examples of liquid?
That really depends on what you mean by a "bad" example of a liquid. In one way you might say urine is a bad example, but in another way you might say a rock is a bad example.

What might happen if you brick the balloon?
If you throw a brick at a balloon it will probably burst.
Suppose you blow up a balloon and then place in the freezer later you find that the balloon has shurnk and has drops of frozen liquid in it?
with the removal of its heat energy, the air in the balloon became denser so it occupied less space. That's why it shrank.. the frozen liquid was the moisture from the air.. e.g. when warm air hits cool glass, the moisture droplets separate from the air and settle on the glass.. the same thing happened with your balloon the only difference was that your water froze...

What happens to the shape of a helium balloon as it rises?
As the balloon rises, the air pressure outside will decrease, and the balloon skin will deform till the pressure on both sides of the skin is the same. Thus your balloon will inflate in shape, towards the spherical, which is the limiting shape for a simple balloon.
How you know gas is inside the balloon?
If there were nothing inside the balloon - a vacuum - the balloon would quickly collapse due to the pressure of the atmosphere outside it. A firmer structure might resist the air pressure, but not a balloon.
