thermal energy transfer via molecular collisions
thermal energy transfer via fluid movement
thermal energy transfer via electromagnetic waves
For a pure substance, the most stable form of the substance at 1 atm and a specified temperature, usually 25°C: for a gas, 1 atm; for a solution, concentration of 1 molar.
a system's capacity to do PV work
the stablest form of the element under standard thermodynamic conditions
standard enthalpy of formation
the enthalpy change that accompanies the formation of one mole of a compound at 25 C from its elements, with all substances in their standard states at that temperature
heat of reaction
Change of heat = Potential Energy of product minus Potential energy of reaction
total enthalpy in a system is equal to the sum of the steps of the reaction
a reaction with a negative heat of reaction, releases heat
a reaction with a positive heat of reaction, absorbs heat
(thermodynamics) a thermodynamic quantity equal to the internal energy of a system plus the product of its volume and pressure
nature's tendency to make the most probable situation that can occur in a system
the point at which the universe has maximum entropy
Gibbs Free Energy
maximum non-PV Work available for a reaction, deltaG = deltaH - T*deltaS
