At higher temperature, does the fraction of molecules with very low speeds increase or decrease? Explain.

[ f(v) = 4\pi \left( \fracm2\pi k_B T \right)^3/2 v^2 e^-mv^2/(2k_B T) ]

On the same M–B curve, mark approximate positions of ( v_p ), ( \langle v \rangle ), and ( v_rms ). Which is farthest to the right? Application Questions 13. A gas is heated from 300 K to 600 K. Does the peak of the M–B curve move left or right? By what factor does ( v_p ) change?
