Comprehensive Exam Flashcards
Law that states that the total energy remains constant even it is converted from one form to another
FIRST LAW OF THERMODYNAMICS
TYPE OF SYSTEM:
- no energy and mass transfer between the system and the surroundings
ISOLATED SYSTEM
TYPE OF SYSTEM:
- no mass transfer between the system and the surroundings
CLOSED SYSTEM
General Formula for total Internal Energy (for closed systems)
U = Q + W
Property that depends on the amount of matter in a sample
EXTENSIVE PROPERTY
Formula for phase rule
F = 2- π + N
The region of space identified for analysis of open or flowing systems
CONTROL VOLUME
The highest pressure and temperature at which a pure chemical species is observed to exist in vapor/liquid equilibrium
CRITICAL POINTS
Point at which three phases coexist in equilibrium
TRIPLE POINT
The fractional increase in volume of a solid, liquid, or gas per unit rise in temperature
VOLUME EXPANSIVITY
The fractional differential change in volume due to a change in pressure
ISOTHERMAL COMPRESSIBILITY
TRUE OR FALSE
Ideal heat capacities increase with increasing temperature.
TRUE
The energy required to change the temperature of a substance with no phase change
SENSIBLE HEAT
Energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature
LATENT HEAT
An equation that allows us to estimate the vapor pressure at another temperature, if the vapor pressure is known at some temperature, and if the enthalpy of vaporization is known
