In engineering, we are almost always trying to do one of two things:
Engineering thermodynamics classifies heat transfer into three distinct mechanisms: engineering thermodynamics work and heat transfer
The area under the curve on a $PV$ diagram represents the work done during a process. This visual aid reveals a crucial insight: In engineering, we are almost always trying to
(The change in internal energy equals the heat added minus the work done by the system.) Why does this matter? engineering thermodynamics work and heat transfer
In everyday language, "work" means any effort. In engineering thermodynamics, has a very specific meaning: energy transferred across the boundary of a system that can be fully converted into the lifting of a weight.
