Heated air, like what you breath.
Government balloons are just like normal balloons except for the fact that they are used for government purposes. The government will use hot air balloons to transport military supplies, carry weapons, and to travel.
Generally, it is helium. Hydrogen could work, but that would be dangerous.
because of balloons and man mad
The model lung with balloons can be used to demonstrate how the diaphragm and rib muscles work together to expand and contract the lungs, mimicking the process of inhaling and exhaling. As the balloons inflate and deflate, it shows how the lungs fill with air when we breathe in and release air when we breathe out. This hands-on demonstration helps visualize the mechanics of breathing in a simple and interactive way.
there are the ones that work and the ones that don't
Greenhouse gases work the way blankets work, by keeping heat in.
Balloons and rockets are both used for controlled flight, but they operate in different ways. Balloons rely on buoyancy to float and rise, while rockets work by expelling propellant in the opposite direction to generate thrust. Overall, they serve different purposes and are designed for different types of missions.
This relationship between the temperature and volume of a gas, which became known as Charles' law, provides an explanation of how hot-air balloons work
A device to make work easier is a machine, such as a lever.
Weather balloons work by carrying instruments called radiosondes that measure various atmospheric parameters such as temperature, humidity, and pressure as they ascend through the atmosphere. The balloons are filled with helium or hydrogen gas, which causes them to rise and reach high altitudes where the data can be collected and transmitted back to the ground station.
The bell jar is an airtight space. When the rubber diaphragram is pulled the volume of the space increases and air rushes into fill it, therefore expanding the balloons. When the diaphragram is released the volume of the space dcreases and the air in the balloons is pushed out. The balloons deflate.
The energy that is used to make the machine work.
