THERMOCHEMISTRY
A WELL DEFINED PART OF THE UNIVERSE WHERE THERMODYNAMICS PROCESSSES TAKE PLACE
SYSTEM
REFER TO EVERYTHING OUTSIDE THAT IS CLOSE CONTACT WITH THE SYSTEM
SURROUNDINGS
CLOSED SURFACE SURROUNDING A SYSTEM
BOUNDARY
THE SYSTEM PLUS THE SURROUNDING
UNIVERSE
A SYSTEM WHEREIN THERE AN EXCHANGE OF MATTER AND ENERGY WITH THE SURROUNDING
OPEN SYSTEM
A SYSTEM WHEREIN THERE AN EXCHANGE OF ENERGY WITH THEB SURROUNDING BUT MATTER IS NOT ABLE TO PASS THE BOUNDARY
CLOSED SYSTEM
A SYSTEM WHEREIN THERE IS NO EXCHANGE OF THE MATTER AND ENERGY WITH THE SURROUNDING
ISOLATED SYSTEM
A REACTION THAT THE SYSTEM ABSORBS HEAT ORN HEAT FLOWS INTO THE SYSTEM SURROUNDING
ENDOTHERMIC REACTION
A REACTION THAT REALEASES HEAT FROM THE SYSTEM INTO THE SURROUNDING
EXOTHERMIC REACTON

RUDOLF CLAUSIUS AND WILLIAM THOMSON
REFER TO THE OVERALL ENERGY OF THEBSYSTEM SUCH AS POTENTIAL AND KINETIC ENERGY.
INTERNAL ENERGY ( U OR E)
THE QUANTITY OF ERNRGY EXCHANGED BETWEEN A SYSTEM AND ITS SURROUNDING
WORK (W)
