3.Kinetic Molecular Theory explains the properties and behavior of gases. One of its statements describe gases to have negligible mass and volume. How can you possibly prove the previous statement
One way to prove that gases have negligible mass and volume is through the ideal gas law, which states that the pressure, volume, and temperature of a gas are related by the equation PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the ideal gas constant, and T is temperature.
According to the ideal gas law, the volume of a gas is directly proportional to the number of moles of gas present. This means that as the number of moles of gas increases, the volume occupied by the gas will also increase. Conversely, if the number of moles of gas is reduced, the volume of the gas will also decrease.
Since gases have negligible mass and volume, this means that the number of moles of gas present in a gas sample is very small, and therefore the volume occupied by the gas is also very small. This results in gases being able to expand and fill the container they are in, regardless of the size of the container. Additionally, gases can be compressed to very small volumes because the particles in a gas are in constant, rapid motion and have little to no attractive forces between them.
Overall, the negligible mass and volume of gases can be observed through the properties and behavior of gases as described by the ideal gas law.
