1 I. Off, selected in the experiment of choosing cloth Lang Lang. The following statements are correct: A. The figure records the situation of molecular irregular movement B. The picture records the situation of particles doing Brownian motion. C. Experiment It can be seen that the larger the particles, the more obvious the Brownian motion. D. As can be seen in the experiment, the higher the temperature, the more intense the Brownian motion. 2. If M represents the molar mass of water, v represents the molar volume of water vapor under standard conditions. ,?
