Why do we calculate work in thermodynamics?

[106029153]

By calculating work we are able to see how a thermodynamic system interacts with its surroundings and how energy is exchanged, since work is energy in motion.

[Julianne Morris 2C]

It is easy to understand the importance of work in a mechanical sense, where energy is transferred from one place to another using force. Work holds a similar meaning in terms of thermodynamics, where energy in a thermodynamic system is transferred into another thermodynamic system. When we calculate work in a thermodynamic system, we are able to see how energy is exchanged, and how the system interacts with other systems and its surroundings.

In thermodynamics, work allows one to observe how a system is able to exchange energy with its surroundings and this exchange of energy is a way for the system to exert forces or work onto the surroundings.
