Which of the following statements is not true? — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

mean speed c_avg = √(8rt/πm) → (c_avg)^2 = 8rt/πm ≈ 2.54 rt/m. mean square speed is u^2 = 3rt/m. since 2.54 rt/m ≠ 3rt/m, the square of the mean speed is not equal to the mean square speed. thus, statement (b) is incorrect.
