Question
Chapter 2, Problem 2.50CU

Explain why work is not a property of the system.
If a closed system undergoes a process during which it receives energy by heat transfer and work
is done on the system, the total energy of the system must increase.
If the energy crossing the boundary of a closed system is not heat, it must be work?
