The formulas for the three speeds mentioned here can be derived by mathematical techniques. The most probable speed is the square root of (2 R T / M), where R = gas constant, T = temperature, M = molecular mass. For the gas N 2, which temperature gives the highest most probable speed: 500 C, 600 K, or 700 F?
