Thermodynamics Flashcards
Studies the transfer of heat and the interconversion of heat and work in various physical and chemical processes.
Thermodynamics
Transfer of energy and work in macroscopic systems that is, without any consideration of the nature of the forces and interactions between microscopic individual particles.
Classical Thermodynamics
Links the atomic nature of matter on a macroscopic level with the observed behavior of materials on the macroscopic level
Statistical thermodynamics
Focuses on energy transfer during chemical reactions, and on the work done by chemicals
Chemical Thermodynamics
First reaction turbine was described by ___________
Hero of Alexandria
Branch of physical science that treats of various phenomena of energy and the related properties of matter, especially of the laws of transformation of heat into other forms of energy and vice versa.
Thermodynamics
___________ is the pressure difference between system’s absolute pressure and surrounding absolute pressure where the device is located
Gage Pressure
Measure of speed of the molecules of a body
Temperature
_______ states that when two bodies are in thermal equilibrium with a third body then they are in thermal equilibrium with one another
Zeroth law of thermodynamics
Work done by force of gravity should the body move from the datum elevation to another
Gravitational Potential Energy
Energy as a result of its motion relative to some reference frame
Kinetic energy
Energy which is the sum of all microscopic forms of energy of a system
Internal energy
The portion of internal energy of a system associated with the kinetic energy of the molecules.
Sensible energy
The internal energy associated with the phase of the system
Latent energy
The internal energy associated with the atomic bonds in a molecule.
Chemical or bond energy
An energy interaction between a system and its surroundings.
Work
Work done per unit time
power
________ is work done in pushing a fluid across a boundary usually into or out a system
Flow work
Form of energy that is transferred between two system bu virtue of temperature difference
Heat
Processing during which there is no heat transfer
Adiabatic process
Energy transmission with a rotating shaft
Shaft work
