Is filling a balloon with hot air a chemical or physical change?
Filling a balloon with hot air is a physical change because the hot air is simply expanding and occupying more space within the balloon, without any change in its chemical composition.
Is a hot air balloon rising a chemical change?
No, a hot air balloon rising is a physical change, not a chemical change. The balloon rises because the air inside it is heated, causing it to expand and become less dense than the surrounding air, which causes it to float upwards.
How does the volume in a hot air balloon change?
The volume of a hot air balloon increases as the air inside the balloon expands when it is heated. As the balloon ascends and the air temperature decreases, the volume of the air inside the balloon decreases as well. The pilot can control the altitude of the balloon by controlling the temperature of the air inside.
Is a hot air balloon a chemical change?
No, a hot air balloon involves physical changes such as heating and expanding the air inside the balloon, without involving any chemical reactions.
Is Filling up a balloon with hot air chemicle or physical change?
Filling up a balloon with hot air is a physical change. The hot air causes the particles within the balloon to expand and increase in kinetic energy, leading to an increase in pressure inside the balloon. Once the balloon cools down, the particles contract, causing the balloon to deflate, but no new substances are formed.
How did things change because of the hot air balloon?

How did hot air balloons change the world?
The hot air balloon changed the world's method of transportation. This balloon was now a method of travel that didn't exist before.
How do you guide the hot air balloon?
You change the volume or the weight of the balloon to raise it or lower it into air currents that are traveling where you want to go.
Why does a hot balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
What is the technique used to pilot a hot air balloon?
Hot air balloonists use the torch to change the amount of hot air in the balloon, changing it's height (hot air rises, cool air sinks). By finding the right wind (northward, southward, etc.) the balloonist can change the direction they choose to go.
Why does a hot air balloon fly?
A hot air balloon flies because hot air inside the balloon is less dense than the cooler air outside. This temperature difference creates lift, allowing the balloon to rise and float in the air. By controlling the temperature of the air inside the balloon, the pilot can control the balloon's ascent and descent.
Why is an hot air balloon called a hot air balloon?
A hot air balloon is called such because it is filled with hot air to make it rise. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to float upwards.
