Latent heat of vaporizationV. Photic zone Current LectureI. Why does water dissolve an unusual amount of salta. NaCl i. Is a polar molecule 1. Attract opposite charges, like water2. Can attract and form hydrogen bonds with waterii. Salt water dissolves 1. DissolutionII. Non-polar bondsa. Cannot form hydrogen bonds wither water b. Ex: oilIII. Heat Capacity a. Amount of energy necessary to raise one gram of substance one degree Ci. The river will be cooler than the parking lot on a hot summer day1. Water has a high heat capacity 2. Parking lot has a low heat capacity IV. Latent heat of vaporization a. Amount of energy it takes to convert one gram of a liquid at the boiling temperature to 1 gram of gas at the boiling temperature b. Latent heat of fusion would be the same thing but from a solid to a liquid V. Photic zone These notes represent a detailed interpretation of the professor’s lecture.
