The presence of a solute affects the physical properties of the solvent. For instance, when salt is spread on icy sidewalks, a mixture is created with a lower freezing point than that of pure water and the ice melts. In this part of the chapter we explore the molecular nature of these effects and see how to treat them quantitatively. 

As the other officer approached, Burns yelled "Watch your back " causing the officer to turn around, but no one was there.

There exists in every city a symbiotic relationship between the city and its art. When we hear the term art, we tend to think of private art—the kind displayed in private spaces such as museums, concert (1V halls, and galleries. But there is a growing interest in, and respect for, public art the kind of art created for and displayed in public spaces such as parks, building lobbies, and sidewalks.
