Thermochemistry & Thermodynamics
10 terms
Second Law of Thermodynamics
The total entropy of the universe increases in every spontaneous process.
Thermochemistry & ThermodynamicsSpecific Heat Capacity
The heat required to raise the temperature of one kilogram of a substance by one kelvin.
Thermochemistry & ThermodynamicsSpontaneity
The tendency of a process to occur without any continuous external input of energy.
Thermochemistry & ThermodynamicsStandard Enthalpy of Combustion
The enthalpy change when one mole of a substance burns completely in excess oxygen under standard conditions.
Thermochemistry & ThermodynamicsStandard Enthalpy of Formation
The enthalpy change when one mole of a compound forms from its elements in their standard states.
Thermochemistry & ThermodynamicsStandard Molar Entropy
The absolute entropy of one mole of a substance in its standard state at 298 K.
Thermochemistry & ThermodynamicsStandard State
The reference condition of a pure substance at 1 bar pressure and a stated temperature, conventionally 298.15 K.
Thermochemistry & ThermodynamicsState Function
A property whose value depends only on the current state of the system, not on how that state was reached.
Thermochemistry & ThermodynamicsSurroundings
Everything outside the chosen system with which it can exchange energy or matter.
Thermochemistry & ThermodynamicsSystem
The specific part of the universe chosen for thermodynamic study, separated from everything else by a real or imaginary boundary.
