Recall from Section 14.3 that the average kinetic energy of an atom in a monatomic ideal gas is given by KE=(3/2)kT, where k = 1.38 x 10-23 J/K and T is the Kelvin temperature of the gas. Determine the de Broglie wavelength of a helium atom (mass = 6.65 x 10 -27 kg) that has the average kinetic energy at room temperature (295 K). Number i Units
