Thermochemistry & Thermodynamics
Heat
Energy transferred between a system and its surroundings solely because of a temperature difference.
Thermochemistry & ThermodynamicsHeat Capacity at Constant Pressure
The heat needed to raise a system's temperature by one kelvin while pressure is held constant.
Thermochemistry & ThermodynamicsHeat Capacity at Constant Volume
The heat needed to raise a system's temperature by one kelvin while its volume is held fixed.
Thermochemistry & ThermodynamicsHelmholtz Free Energy
The thermodynamic potential that determines spontaneity at constant temperature and volume.
Thermochemistry & ThermodynamicsHess's Law
The total enthalpy change of a reaction is the same regardless of the route taken, provided the initial and final states are identical.
