Expansion
The three videos below cover different aspects of Expansion. The first videos covers work from expansion, including how a system can do work by expanding. The second video looks at PV-diagrams and expansion work, including why work from expansion is the area under the curve of a PV-diagram. The third video looks at conceptual proof that the internal energy of an ideal gas system is 3/2 PV.
