One cubic meter (1 m³) of mono-atomic ideal gas, is initially at room temperature and atmo- spheric pressure. The mass of a single molecule is 1.34 × 10-26 kg. 1. Find the root mean square speed, vrms, Oof the molecules by equating the kinetic energy of a single molecule to its average thermal energy. 2. Knowing that the gas obeys the Maxwell speed distribution 3/2 4nv²e-2T m mu2 D(v) = (0.2) 2πkT such that D(v)dv = 1. (0.3) Find the expression of the probability (do not do the integral) that a particular molecule is moving with a speed faster than 2000m/s. 3. The gas is heated at constant pressure until it triples in volume. Calculate the increase in its entropy.
