Answers & Comments
Answer:
1. Soy sauce added and mixed with (a generous amount) water will spread out to its equilibrium until the solution is homogenous. The solids inherent in the soy sauce may further be dissolved in solution and stay suspended in the water, until such conditions would precipitate it (eg low temperatures).
2. ------------------
3. Continuesly dissolve in the water.
4. -----------------
5. Particles in all states of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. ... Individual particles in liquids and gases have no fixed positions and move chaotically.
