Engineering Thermodynamics Work And Heat Transfer |top|

Work is considered "high-grade" energy because it can be 100% converted into heat. Common forms include: Occurs in quasi-equilibrium processes, calculated as

is the change in (molecular-level kinetic and potential energy). is the net heat transfer. is the net work transfer. Common Ideal Processes The calculation of depends on the process path: Isobaric (Constant Pressure) : Isochoric (Constant Volume) : Isothermal (Constant Temperature) : For an ideal gas, Adiabatic (No Heat Transfer) : 4.

Energy transferred solely due to a temperature difference between a system and its surroundings. It naturally flows from hotter to colder regions. Work is considered "high-grade" energy because it can

Thermodynamics distinguishes between two transient forms of energy that cross a system boundary: Heat ( is the net work transfer
