Closed Thermodynamic System Definition
A closed thermodynamic system is defined as a system where mass cannot transfer across its boundaries, but energy can.
Energy Transfer in a Closed System
Energy can be transferred across the system boundary in two primary forms:
- Heat: Energy transfer due to a temperature difference.
- Work: Energy transfer due to a force acting over a distance.
Since a closed system allows for energy transfer but not mass transfer, both heat and work can cross its boundaries.
Conclusion
Therefore, in a closed thermodynamic system, the transfer of heat and work is possible across its boundaries.
