On Friday we took the 2-dimensional heating/cooling curves we talked about on Wednesday and translated them into a phase diagram that relates pressure and temperature to the states of matter for a substance. Although understanding how pure substances behave is important, the majority of "matter" we encounter is not pure substance but various mixtures, so we started talking about solutions and how addition of a solute can change physcial properties. These colligative properties depend upon the number of solute particles present in the solution, not the identity of those solute particles.
See you all on Wednesday. (or Tuesday if you're in my lab section...)
