When does a air balloon rise?
A hot air balloon rises because when hot air is added it is intended to rise and when the hot air balloons wants to land, hot air is decreased.
Why does heating the air in hot air balloon make it rise?
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
Does hot air rise or fall?
Hot air rises
Why does a hot air balloon rise when the air inside it is heated?
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
Does hot and cold air fall or rise?
Hot air rises and cold air falls.
Do liquids expand?
Yes. liquids expand. If we heat the beaker which is filled with water using a candle, the volume will rise as the water is mixed with hot air. Hot air would want to excape, therefore liquids do expand.
Does heat rise or hot air rise?
Heat is the energy of the hot air. Therefore hot air rises
Why does pressure in tires increase on hot days?
Because if you heat a gas (the air in the tyre) without letting it expand the pressure will rise.
Why balloons expand when placed in hot water?
The hot water heats the air inside the balloon - making it expand.
When does a air balloon rise?
A hot air balloon rises because when hot air is added it is intended to rise and when the hot air balloons wants to land, hot air is decreased.
Why does heating the air in hot air balloon make it rise?

Does hot air rise or fall?
Hot air rises
Why do you think hot-air balloons can rise into the air?
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
Why do hot air balloons rise with hot air?
Hot air is less dense than cooler air, therefore the balloon will rise (float) on the cooler air around it.
Will a balloon rise higher with hot air or cold air?
Hot air
Why does a hot air balloon rise when the air inside it is heated?
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
How does particle theory explain the formation works in a hot air balloon?
A gas burner is used in the hot air balloon to heat air. When heat is applied, particles tend to expand. Due to this the air surrounding the balloon is cooler than the air inside it, making it to rise.
