In this article, we will discuss the work transfer and heat transfer properties and also some similarities between both of them then the difference between them.
Points to remember regarding heat transfer and work transfer :
- Work and heat transfer both are energy interactions.
- The same effect in a closed system is about either by heat transfer or by work transfer.
- Both heat transfer and work transfer are boundary phenomena.
- Heat transfer is one type of energy interaction and it is due to temperature difference. All other energy interactions may be termed as a work transfer.
- Heat or work is not a property of the system. It cannot be stored by the system. Both heat and work are energy in transit.
- Both heat and work are path functions and inexact differentials.
- The magnitude of heat transfer or work transfer depends upon the path of the system that follows during the change of state.
Difference between heat transfer and work transfer :
Heat transfer is an interaction of energy between a system and its immediate surrounding due to temperature difference.
Work transfer is the interaction of energy between a system and its immediate surrounding due to property difference other than temperature.
