Question
A gas absorbs $45 \mathrm{~kJ}$ of heat and does $29 \mathrm{~kJ}$ of work. Calculate $\Delta E$.
Step 1
We know that the change in internal energy (ΔE) of a system is given by the first law of thermodynamics: ΔE = Q - W, where Q is the heat absorbed by the system and W is the work done by the system. Show more…
