Heat expands the gas (any gas) and makes the balloon rise.
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
The solid would be the basket and balloon, and the tanks holding flammable gas. The liquid is water vapor released by burning the gas. The gases are the fuel in the tank, and the heated air in the balloon that causes it to rise.
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.
a hot air ballon uses the hot air to rise as the hotter air has lower density while a gas ballon contains a light gas such a s helium and is not released while in flight only added
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.

Simple...hot air rises..
It is filled with a gas that is lighter than air.
Helium gas in the balloon causes it to rise as it is much less dense than the surrounding air which has heavier molecules such as Oxygen, Nitrogen, Carbon Dioxide, etc.
because as you heat the gas, you cause the gas to expand on the container (whish is a balloon), this lowers the density, and a less dense fluid submersed in a denser fluid will rise, like an air bubble rises from underwater
The solid would be the basket and balloon, and the tanks holding flammable gas. The liquid is water vapor released by burning the gas. The gases are the fuel in the tank, and the heated air in the balloon that causes it to rise.
Hot air rises more quickly than cold air, so when you heat the air inside the balloon, it cant escape, so it pushes the balloon up.
