How to calculate rms speed?
Understand the Problem
The question is asking for the method to calculate the root mean square (RMS) speed, which is a statistical measure used in physics to determine the average speed of particles in a gas. It involves understanding both the formula and the necessary variables involved in the calculation.
Answer
v_rms = √(3RT/M) or v_rms = √(3KT/m)
The final answer is v_rms = √(3RT/M) or v_rms = √(3KT/m)
Answer for screen readers
The final answer is v_rms = √(3RT/M) or v_rms = √(3KT/m)
More Information
The RMS speed (Root Mean Square speed) of gas molecules is a measure of the speed of particles within a gas which is useful in kinetic theory.
Tips
A common mistake is confusing molar mass (M) and molecular mass (m). Ensure you use the correct value for the formula you are using.
