What does a balloon do when heated?
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
Why doesn't an inflated balloon shrink when heated?
Because as the balloon is heated, the gases on the inside of the balloon begin to expand and press out on the walls of balloon. If a balloon is refridgerated, the opposite is true: the gases on the inside of the balloon will begin to contract, causing the balloon to shrink.
When a helium balloon rises in the air it expands. If the volume of the balloon doubles what happens to the density of the helium inside it?
The density will be 50 % from the initial value.
Why does the volume of a balloon increase as the balloon is heated?
Because the gas inside expands with the heat
What if a balloon is heated what happens to the volume of the air in the balloon if the pressure is constant?
For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. If the air inside the balloon is heated the air inside becomes less dense so some of the air exits the balloon via the mouth of the balloon. As the air inside the balloon cools it becomes more dense so some air is ingested via the mouth of the balloon to keep it full. With each heating and cooling cycle, the pressure inside the balloon remains constant, the volume of the balloon remains constant but there is this movement of air out of and back into the balloon.

Does heat from a candle change air pressure inside a bag?
yes because pressure that is confined by a container such as a balloon will increase if the balloon is heated.

Why does a hot air balloon rise when the air is heated?
the heated air inside of the balloon has less density than the cold outside air so the hot air is more buoyant (e.g. the bowling ball sinks but the beach ball floats because the density of the beach ball is less than the water)
When a helium balloon rises in the air it expands. If the volume of the balloon doubles what happens to the density of the helium inside it?
The density will be 50 % from the initial value.
What forces magma to Earth's surface?
Generally, its higher temperature. The temperature of a rising magma is generally higher than the temperature of its surrounding rocks. Because of its higher temperature, it is also lighter compared to the surrounding rocks (it has a lower density), so it rises. Imagine a hot air balloon: it rises because the air inside the balloon is heated, heating the air lowers its density (makes it lighter). As long as the density of the air inside the balloon is lower than the density of the air outside the balloon, the balloon rises.
Why does the volume of a balloon increase as the balloon is heated?
Because the gas inside expands with the heat
What will happen to a balloon's volume if its heated?
The kinetic energy of the particles inside the balloon increase. This then expands the volume of the balloon.
Is an air inside a balloon a pure substance?
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
What kind of fuel is used for the hot air balloon?
Propane gas is used to fuel the burners that heat the air inside the balloon.A hot air balloon is filled with regular air that's heated by a propane burner. This heated air has a lower density than the air outside the ballon, thus allowing the filled balloon to be buoyant.

What can you say about the gas inside a balloon?
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
