Correct)
system - ANSWER part of the universe in which we are interested
open system - ANSWER can exchange energy and matter across its boundaries
closed system - ANSWER can exchange energy, not matter across its boundaries
isolated system - ANSWER can exchange neither energy nor matter across its boundaries
properties - ANSWER any measurable quantities characterizing a system

intensive properties - ANSWER independent of mass of system
state of a system - ANSWER specificiation of a certain number of variables (ex: mass, identity, state
of matter, temperature, pressure, volume etc.)
equation of state - ANSWER P = f (nvt)
ideal/perfect gas - ANSWER one where molecules possess negligible volume, and where there is no
interaction or repulsive among molecules
