What is Lecture Capture?. Lecture Capture is the use of a set of technologies to capture and then enable time-shifted and place-shifted viewing of the Lecture Content.. Assembly Language and . Arduino. Behind the C code (or sketch). C provides a somewhat human-readable interface. but it gets . compiled. into machine instruction set. ultimately just binary (or hex) instructions loaded into the . Chapter 17. Pages 511-524. Phase Diagrams. -a graph of pressure vs. temp that shows the conditions under which the phases of a substance exist. Triple point – . indicates the T and P conditions at which the solid, liquid, and vapor of the substance coexist at eq. 1. The LHC Voyage . Of. Discovery . Dan Green. Fermilab.

Study of energy changes that occur during chemical reactions and changes of state. Endothermic. Process that absorbs/gains heat. Heat flows into the system (+q). Heat removed from the surroundings (-q). A form of energy. Flows from warmer objects to cooler objects. Represented by the variable “q”.
