a) the entropy change of the boiling water
b) the total entropy change of the entire system
2.Smoke particles in the air typically have masses of the order of 10-16 kg. The Brownian motion (rapid, irregular movement) of these particles, resulting from collisions with air molecules, can be observed with a microscope.
(a) Find the root-mean-square speed of Brownian motion for a particle with a mass of 3.00 X 10-16 kg in air at 300 K.
(b) Would the root-mean-square speed be different if the particle were in hydrogen gas at the same temperature? Explain.
