WebNov 3, 2016 · Calculate the change in internal energy of the gas. First, I used the equation: change in $E = q + w$. 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. WebThere is a change in the thermal store of energy within the material.
