LAWS OF THERMODYNAMICS Flashcards
Any object or collection of objects with a capacity for energy transfer is referred to as a
thermodynamic system
can exchange both energy and matter with its surroundings
Open System
can exchange energy with its surroundings, but its wall does not permit the exchange of matter
Closed System
does not interact with its surroundings since its
wall is impermeable to both energy and matter
Isolated System
the branch of physics that
deals with the transfer of thermal energy
Thermodynamics
deals with thermal energy, internal energy, and work
first law of thermodynamics
defined as the sum of the kinetic energies of all the particles in the system and the sum of all the potential energies of the interaction of the particles.
Internal Energy
defined as the energy of the
system due to the movement of the particles
Thermal or heat energy
