## 2.2 Corollaries of the First Law
- Work done in any adiabatic (
) process is a function of state.
We can write the first law, setting the heat transfer
term equal to zero, as
(2..3) Since depends only on the state change, now can be found as a function of the state change. - For a cyclic process heat and work transfers are numerically equal
**Figure 2.4:**Since energy is a function of state only, any process that returns a system to its original state leaves its energy unchanged. therefore and
