pHySiCs


so today we were driving on the road and we happened to pass a gas station.  When I saw people filling up gas I immediately though about car engines and how they work.  Gas molecules are put inside the valves of the engine where they are ignited by an electrical spark.  The pressurized gas combusts and pushes the piston which does work.  This is all related to our recent study of gases and thermodynamics.  I also thought about how high gas prices were and how the world would be in a better place if car engines were 100% efficient.  We could probably travel more than twice as much if that were possible!
