Document Summary
T: temperature (in k) m: mass of the molecule (in kg) M: molar mass of the molecules (in kg/mol) Increasing temperature (t), increases the most probable (mp) speed, the average speed, and the root mean square (rms) speed of a sample molecule, thus, increases the total kinetic energy. For an ideal gas, the average kinetic energy per molecule of an ideal gas is given by the equation. = 3/2k_bt, and the average kinetic energy per mole is = 3/2rt. Temperature is proportional to the average kinetic energy of molecules. 1a) on the plot above, label the most probable speed ( ) of ne atoms in a gas at 298k. Answer: approximately 500 m/s (the speed at which f(v) is at its maximum). , , and of ne atoms in a gas at 298 k. The root mean square speed is the greatest ( Answer: the maximum will be lower and shifted to the right.
