Question

Consider your own body as the thermodynamic system for this question and assume the first law of thermodynamics is given as $\Delta U = Q - W$. Imagine lifting a very heavy weight very slowly from the floor until it is overhead. Over the duration of this process, what would be the signs of Q and W for your body? Q<0, W<0 Q>0, W<0 Q<0, W>0 Q>0, W>0 I DON'T KNOW YET

Step 1

Here: - $\Delta U$ is the change in internal energy of the system (your body). - $Q$ is the heat added to the system. - $W$ is the work done *by* the system. Step 2: Analyze the work done (W) by your body. You are lifting a very heavy weight from the floor until Show more…
