THERMODYNAMICS
13
Thermodynamics: moving or evolving heat
Internal energy: refers to the sum o the kinetic energy of the molecules of a body and the potential energy due to intermolecular forces
Zeroth law: this law was first formulated by R.H. Fowler
Kelvin: ______ - Planck Statement tells no heat engine can completely convert heat energy to work
Clausius: ________ Statement tells heat flows naturally from hot to cold objects
Entropy: is the thermodynamic measure of disorder
Absolute zero: is the temperature at which molecules stop moving
Heat engine: device that converts heat energy to mechanical work
Carnot engine: a hyothetical engine where all processes are reversible
Reversible process: is one in which the system and its surroundings can be turned to exactly the initial states they were in before the process takes place
System: is an object or collection of objects under study
Joules: work are expressed in ______
Gasoline engine: also known as Otto engine
Maximum: _______ efficiency is obtained if all the processes undergone by the working substance of a heat engine are reversible.
