Name the gas which is filled in balloons

\( \newcommand\) • • • • Skills to Develop • To understand the relationships among pressure, temperature, volume, and the amount of a gas. Early scientists explored the relationships among the pressure of a gas ( P) and its temperature ( T), volume ( V), and amount ( n) by holding two of the four variables constant (amount and temperature, for example), varying a third (such as pressure), and measuring the effect of the change on the fourth (in this case, volume). The history of their discoveries provides several excellent examples of the The Relationship between Pressure and Volume: Boyle's Law As the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together. Conversely, as the pressure on a gas decreases, the gas volume increases because the gas particles can now move farther apart. Weather balloons get larger as they rise through the atmosphere to regions of lower pressure because the volume of the gas has increased; that is, the atmospheric gas exerts less pressure on the surface of the balloon, so the interior gas expands until the internal and external pressures are equal. The Irish chemist Robert Boyle (1627–1691) carried out some of the earliest experiments that determined the quantitative relationship between the pressure and the volume of a gas. Boyle used a J-shaped tube partially filled with mercury, as shown in Figure 5.2.1. In these experiments, a small amount of a gas or air is trapped above the mercury...

While there are a variety of gases that could theoretically be used to fill a balloon, the vast majority of balloons are filled with either helium or air. There are a number of reasons for this. Helium is significantly lighter than air, which means that it can make a balloon float. This is often desirable for decorative purposes. Air is significantly cheaper than helium, which makes it a more practical choice for many applications. Helium can leak out of a balloon more easily than air, which means that it may not be able to maintain its shape for as long. Air is less flammable than helium, which makes it a safer choice. In conclusion, while there are other gases that could be used to fill a balloon, helium and air are by far the most common choices. There are a number of reasons for this, including the fact that they are relatively inexpensive and safe. A balloon can float in the air as long as it is made of low-density materials. Hydrogen is half the density of helium, allowing it to float more easily. Balloon filling is accomplished by utilizing balloon booster. Lift gas is used in the United States for helium flights, such as those involving hydrogen. Each of these gases is less dense than air. A gas balloon’s first step is to lift from helium or inject hydrogen into its envelope. Why Is Hydrogen Gas Not Used In Balloon?
