Internal Energy definitions Flashcards

Total kinetic and potential energy within a system, calculated as the sum of heat and work.

Symbol representing internal energy, interchangeable with Delta U.

Alternative symbol for internal energy, equivalent to Delta E.

Energy transferred due to temperature difference, represented by Q.

Energy transfer resulting from a force acting over a distance, calculated as negative pressure times change in volume.

Force exerted per unit area, measured in atmospheres in this context.

Space occupied by a substance, measured in liters.

Unit of work, convertible to joules using a factor of 101.325.

SI unit of energy, used to express internal energy, heat, and work.

Heat change during a reaction at constant pressure, represented by Delta H.

Symbol for enthalpy, equivalent to heat at constant pressure.

Energy associated with the motion of particles within a system.

Energy stored within a system due to position or arrangement of particles.

Process involving rearrangement of molecular or ionic structure, affecting enthalpy.

Numerical factor used to convert units, such as 101.325 for liters-atmospheres to joules.
