Introduction:
In deriving the kinetic gas equation, the root mean square velocity of the molecules is used because it provides the most accurate form in which velocity can be used in these calculations.

Explanation:
The kinetic gas equation, also known as the ideal gas law, relates the pressure, volume, and temperature of a gas to its molecular properties. It is given by the equation:

PV = NkT

Where:
- P is the pressure of the gas
- V is the volume of the gas
- N is the number of gas molecules
- k is the Boltzmann constant
- T is the temperature of the gas

Root Mean Square Velocity:
The root mean square (RMS) velocity is defined as the square root of the average of the squared velocities of the gas molecules. It is given by the equation:

v(rms) = √(3kT/m)

Where:
- v(rms) is the root mean square velocity
- k is the Boltzmann constant
- T is the temperature of the gas
- m is the mass of a gas molecule

Why Root Mean Square Velocity is used:
The root mean square velocity is used in the kinetic gas equation because it represents the most accurate form of velocity for gas molecules. Here's why:

1. It considers the distribution of velocities: The molecules in a gas have different velocities, and their distribution follows the Maxwell-Boltzmann distribution. The root mean square velocity takes into account this distribution by considering the average of the squared velocities.

2. It is related to kinetic energy: The kinetic energy of a gas is directly proportional to the square of its velocity. The root mean square velocity provides a direct measure of the kinetic energy of the gas molecules.

3. It is experimentally verifiable: The root mean square velocity can be measured experimentally using various techniques, such as the method of effusion or diffusion. This makes it a reliable and practical quantity to use in calculations.

4. It is consistent with the ideal gas assumptions: The kinetic gas equation is derived based on certain assumptions about gas behavior, including the assumption of random molecular motion. The root mean square velocity is consistent with these assumptions and provides a meaningful representation of the molecular velocities in an ideal gas.

Therefore, the root mean square velocity is the most accurate form of velocity to be used in the kinetic gas equation, making option D the correct answer.
