I calculated work ($-P \Delta V$) and found it to be $$-18 = -2 \cdot (10 - 1)$$. Then, I added $-18 + q$, the heat absorbed ($\mathrm {200\,J}$). This gave me a result of $\mathrm {-182\,J}$, which is wrong by a large factor. WebNov 15, 2014 · In classical thermodynamics the change in internal energy is defined by the first law as Δ U = q + w so that only the difference in U is known; q is the heat absorbed by the 'system' and w the work done on the system. For example in a closed system (no exchange of matter with environment) we can write for a reversible change irish national flying club
