2.  The study of and its transformation into  Looking at the macroscopic level of how heat affects our lives  KEY FOUNDATIONAL POINTS

3.  of temperature and of a substance … continues to increase with temperature without an end in sight  can be extracted  of temperature possible  On Celsius scale, absolute zero =

4.  On Kelvin scale,  Kelvin (K) is scale (units) used in  Ice melts @  Water boils @

5.  Looking @ the flow of, it is just the flow of  Combine that with the law of energy conservation to derive first law 

6.  System =  Must always define the in order to identify its and its  Heat of the system  Looking at an engine Some energy is converted to Some energy converted to

7.  if work is done i.e. compression Internal energy will Temperature  if work is done i.e. expanding against surroundings Internal energy will Temperature

8.  Process of compression or expansion of a gas so that a system change of volume work rapidly to prevent of system  Let’s look at Figure 24.4 on page 358 An automobile engine is an excellent example of this process (and the book has a pretty diagram for us )

9.  If work done on a gas by Gas  gets  If gas adiabatically, work is done on its surroundings Internal energy  gets
