don't worry about it
You could write about the history of hot air balloons, the physics behind how they work, different designs and shapes of hot air balloons, or personal experiences and stories from hot air balloon rides.
Rubber balloons are more porous than plastic balloons, so they allow air to slowly escape through the surface more easily. This makes rubber balloons deflate faster compared to plastic balloons, which have a tighter seal and are less permeable to air.
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
The heating of the air through the use of a burner is what makes balloons rise.
Hot air balloons do not directly produce air pollution because they are powered by propane burners that combust the gas cleanly. However, the transportation and support vehicles used to operate hot air balloons can contribute to air pollution through emissions from their engines.
Hot air balloons have evolved over time due to advancements in technology and materials. These changes have improved safety, efficiency, and performance of hot air balloons. Additionally, new innovations have allowed for custom designs and shapes, providing more options for users.
Water balloons are typically made of thinner material than latex balloons, so they can hold less air in comparison. Also, water balloons are designed to hold water, not air, so they may burst if overinflated with air. Latex balloons are designed specifically for holding air and can typically hold more air than water balloons.
When air is heated, that volume of air expands (which is why hot air balloons go up). The hot air has changed in volume, but it is still the same mass.
There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.
Yes, hot air balloons flew first. Though I don't know the exact details, as the history is so diverse, spread over many years, and even includes the candle lit paper hot air balloons released at parties or festivals. It would take some research on the internet to get the full details.
The hot air balloon changed the world's method of transportation. This balloon was now a method of travel that didn't exist before.
hot air balloons, colorful ones what kind of simple quesion is this!
