Question
On increasing the temperature of a gas, the fraction of molecules having speed equal to most probable speed at that temperature
Answer: B
💡 Solution & Explanation
The fraction at most probable speed $f(u_{mp}) \propto 1/\sqrt{T}$. Increasing temperature broadens the curve and lowers the peak height. Therefore, correct answer is B.
