30. What is the reason for your answer above?
</p>
</body>
</html>
<html>There are too many particles crowded into one area, so they move to an area with more room.</html>
<html>Particles in areas of greater concentration are more likely to bounce toward other areas.</html>
<html>The particles tend to move until the two areas have equal concentrations of solutes, and then the particles stop moving.</html>
<html>There is a greater chance of the particles repelling each other.</html>
