Question

What is a molecular velocity??​

Answer 1

Answer:

We use velocity to describe the movement of gas particles, thereby taking into account both speed and direction. The root-mean-square speed is the measure of the speed of particles in a gas, defined as the square root of the average velocity-squared of the molecules in a gas.

Answer 2

The speed of the molecules in a gas is proportional to the temperature and is inversely proportional to molar mass of the gas. In other words, as the temperature of a sample of gas is increased, the molecules speed up and the root mean square molecular speed increases as a result.
