Helium is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas series in the periodic table. Helium is the second lightest element and is the second most abundant element in the observable universe. It is important to study its properties because it has many unique characteristics that make it useful in various applications such as cryogenics, welding, and as a coolant in nuclear reactors.
The root mean velocity of Helium is directly proportional to its temperature. This means that as the temperature of Helium increases, its root mean velocity also increases. This relationship is known as the Maxwell-Boltzmann distribution and is a fundamental concept in understanding the behavior of gases.
The graph of root mean velocity vs temperature in Helium is similar to other gases in that it follows the Maxwell-Boltzmann distribution. However, Helium has a larger root mean velocity compared to other gases at the same temperature due to its low atomic mass and high thermal conductivity.
The peak in the graph of root mean velocity vs temperature in Helium represents the most probable velocity of Helium atoms at a given temperature. This peak is important because it shows the average speed of Helium atoms in a gas sample and is a key factor in calculating other properties of the gas.
The graph of root mean velocity vs temperature in Helium remains the same at different pressures. However, the peak of the graph may shift to the left or right depending on the pressure. This is because pressure affects the average speed of gas particles and can influence the shape of the Maxwell-Boltzmann distribution curve.
