How is the average speed of gas molecules calculated?

Options

  1. ABy measuring the speed of each molecule
  2. BBy adding the minimum and maximum speeds
  3. CBy taking the square of the speed values
  4. DBy summing the individual speeds and dividing by the number of molecules

Correct answer

D. By summing the individual speeds and dividing by the number of molecules

Step-by-step solution

The average speed of gas molecules (uav) is calculated by summing the individual speeds (u1, u2, ...un) and dividing by the number of molecules (n).
