Halliday, Resnick & Walker β The Kinetic Theory of Gases: Problem 91
Most probable speed. A container holds a gas of molecular hydrogen (\(H_2\)) at a temperature of 250 K. What are (a) the most probable speed \(v_P\) of the molecules and (b) the maximum value \(P_{max}\) of the probability distribution function \(P(v)\)? (c) With a graphing calculator or computer math package, determine what percentage of the molecules have speeds between \(0.500v_P\) and \(1.50v_P\). The temperature is then increased to 500 K. What are (d) the most probable speed \(v_P\) of the molecules and (e) the maximum value \(P_{max}\) of the probability distribution function \(P(v)\)? Did (f) \(v_P\) and (g) \(P_{max}\) increase, decrease, or remain the same during the temperature increase?
