HESI A2 Chemistry Questions with Answers and Explanations UPDATED 1. Which of the following substances allows for the fastest diffusion? A. gas B. solid C. liquid D. plasma Explanation: Diffusion is fastest through gases. The next fastest medium for diffusion is liquid, followed by plasma, and then solids. In chemistry, diffusion is defined as the movement of matter by the random motions of molecules. In a gas or a liquid, the molecules are in perpetual motion. For instance, in a quan...
