Section 3 =Solar Collector- are devices that collect solar energy= = = = = =Thermodynamics- is the study of the relationship between thermal energy, heat, and work=

= = = = =First law of thermodynamic- states that the increasin thermal energy of a system equals the work done on the system plus the heat added to the system= = = = = =Second law of thermodynamics- states that is impossible for heat to flow from a cool object to a warmer object unless work is done= = = = = =Heat engine- device that converts thermal energy into work= = = = = =Internal combustion engine- heat engine that burns fuel inside the ingine in the chambers or cylinders=
