Concept introduction:
A gas is made up of many atoms or molecules that move with very high speeds. The kinetic energy of gases is very high. Every molecule or atom present in a gas can have a different velocity. The speed of sound in a gas is less than the speed of sound in vacuum. The speed of sound in a gas,

Concept introduction:
A gas is made up of many atoms or molecules that move with very high speeds. The kinetic energy of gases is very high. Every molecule or atom present in a gas can have a different energy. Therefore, root mean square speed, most probable velocity, and mean velocity are calculated for a gas.
